Season 1

“The Cage”

Episode Number 0
Vina, Captain Pike and Number One
Production Number 001
Season 1
Stardate
Original Airdate

Story
Teleplay Gene Roddenberry
Director Robert Butler

Synopsis
Captain Pike and his crew are lured to Talos IV by a race capable of creating powerful illusions.

Starring
Jeffrey Hunter (Captain Christopher Pike)

Guest Cast
Susan Oliver (Vina)
Leonard Nimoy (Mister Spock)
Majel Barrett (Number One)
John Hoyt (Doctor Phillip Boyce)
Peter Duryea (Lt. Jose Tyler)
Laurel Goodwin (Yeoman Colt)
Meg Wylie (The Keeper)

Notes
This unaired pilot episode was rejected by NBC for being “too cerebral”. This led to the creation of a second pilot, “Where No Man Has Gone Before”.
At the time of production, this original pilot was also known as “The Menagerie.” However, as the series proper has a two-part story of the same title, this episode is usually referred to as “The Cage.” The two-part episide “The Menagerie” features scenes from this pilot episode.
Number One’s name is never given, but her rank is Lieutenant.
It seems odd that Number One is Pike’s first officer when Captain Pike doesn’t like females on the bridge. He mentions more than once that Yeoman Colt is to leave the bridge unless she’s there for a report because she is a woman.

Production Number 006
Season 1
Stardate 1531.1 (Calendar Year 2264)
Original Airdate 9/8/1966

Story
Teleplay George Clayton Johnson
Director Marc Daniels

Synopsis
A shape-shifting, salt-craving creature terrorizes the crew of Enterprise.

Starring
William Shatner (Captain James T. Kirk)
Leonard Nimoy (Lt. Commander Spock)

Guest Cast
Jeanne Bal (Nancy Crater)
Alfred Ryder (Prof. Robert Crater)
DeForest Kelley (Dr. Leonard H. McCoy)

Nichelle Nichols (Lt. Uhura)
Bruce Watson (Crewman Darnell)
Michael Zaslow (Crewman Green)
Vince Howard (Crewman)
Francine Pyne (Nancy III)
Eddie Paskey (Lt. Lesley)

Notes
It seemed really unnecessary to kill the pitiful creature.
After the creature boards the Enterprise in Green disguise, he sees Yeoman Rand carrying a lunch tray, and nibbling from it; when “Green” reaches for the salt, she slaps him away with a “Who do you think you are?!” She continues to the bio-lab and then gives the tray to Sulu! He should have slapped her hand for eating from his plate.
This is the first episode McCoy speaks the infamous “He’s dead, Jim” — referring to Crewman Darnell, the first crewman to die under Kirk’s command of the Enterprise.
Spock is the only character to appear in both the unaired pilot (“The Cage”) and the series.
This is the first appearance of Dr. McCoy, Lt. Sulu, Lt. Uhura, and Yeoman Rand.
This is the first appearance of extra Lt. Lesley, who is uncredited in this episode and doesn’t receive a name until “The Alternative Factor”.
Only William Shatner and Leonard Nimoy are listed as the main cast in the opening credits. James Doohan, George Takei, Nichelle Nichols (and Walter Koenig, Season 2+) were listed as co-stars in the end-credits throughout the series. DeForest Kelley is listed in the end-credits in this season, but becomes a regular cast member in Season 2.

“Where No Man Has Gone Before”

Episode Number 3
Kirk is forced to fight his friend Gary Mitchell
Production Number 002
Season 1
Stardate 1312.4
Original Airdate 9/22/1966

Story
Teleplay Samuel A. Peeples
Director James Goldstone

Synopsis
The Enterprise encounters a record-marker left behind by the S.S. Valiant 200 years ago as it tried to go through an energy barrier at the rim of the galaxy. The Enterprise sets course to the rim of the galaxy, where the energy barrier damages the Enterprise’s engines and causes a strange behavioral change in Kirk’s close friend and Enterprise First Officer, Gary Mitchell, who has gained incredible extrasensory powers and god-like abilities.

Guest Cast
Gary Lockwood (Lt. Cmdr. Gary Mitchell)
Sally Kellerman (Dr. Elizabeth Dehner)
George Takei (Lt. Hikaru Sulu)
James Doohan (Lt. Cmdr. Montgomery Scott)
Lloyd Haynes (Lt. Lloyd Alden)
Andrea Dromm (Yeoman Smith)
Paul Carr (Lt. Lee Kelso)
Paul Fix (Dr. Mark Piper)

Notes
This episode was the second pilot, the first episode produced (not counting the un-aired pilot). It was created nearly a year before it aired and there are numerous differences between this episode and the others, including the ship model, the uniforms, and Spock’s ears and eyebrows. For some reason, it was the 3rd episode aired on NBC.
Gary Mitchell and Elizabeth Dehner were chosen because they had the highest ESP ratings on the ship.
This is the first appearance of Chief Engineer Montgomery Scott.
Sulu is the astro-sciences department head in this episode.
Mitchell kills helmsman Lt. Lee Kelso. (He is the first crewman to die if you go by production order.)
This episode displays some incredibly sexist behavior. Mitchell, the ship’s First Officer, makes a pass at Dr. Dehner and when she rebukes him, he calls her a “walking freezer unit,” which he and Kelso find funny. I guess this behavior was acceptable in the 60’s, but it seems very “un-Starfleet”.
The Enterprise is at the rim of the Galaxy in this episode. That would be approximately 25,000 light years from Earth. Later information about the capabilites of the starships would render this trip impossible — it would take 25 years for the Enterprise to travel this distance, and another 25 to return.
When Mitchell creates Kirk’s tombstone, it is labeled JAMES R. KIRK. It will later be established that Kirk’s middle initial is T. (Apparently, Gary does not know Kirk’s middle name.)

“The Naked Time”

Episode Number 4
Lt. Sulu threatens the bridge with a fencing foil
Production Number 007
Season 1
Stardate 1704.2
Original Airdate 9/29/1966

Story
Teleplay John D.F. Black
Director Marc Daniels

Synopsis
The Enterprise is sent to planet Psi 2000 to pick up a scientific team and to observe the dying planet in its final stages. A member of a landing party investigating the ruins on the collapsing planet contracts an unknown infection and returns it to the Enterprise, where it begins to spread rapidly among the crew. Dr. McCoy works to find an antidote before the crew goes out of their minds.

Guest Cast
Stewart Moss (Lt. Joe Tormolen)
Majel Barrett (Nurse Christine Chapel)
Bruce Hyde (Lt. Kevin T. Riley)
DeForest Kelley (Dr. Leonard H. McCoy)
Grace Lee Whitney (Yeoman Janice Rand)
George Takei (Lt. Hikaru Sulu)
James Doohan (Lt. Cmdr. Montgomery Scott)
Nichelle Nichols (Lt. Uhura)
William Knight (Amorous Crewman)
John Bellah ([Dr. Harrison)
Frank da Vinci (Lt. Brent)

Notes
After Riley shuts down the engines, Scotty has to start them up in less than standard 30 minutes to prevent the Enterprise from crashing into Psi 2000. The new procedure that he and Spock creates starts the engines successfully, but it sends them backwards in time.
This is the first appearance of Nurse Chapel, played by Gene Roddenberry’s wife, Majel Barrett. Chapel has a crush on Spock. Majet Barrett previously played “Number One” in the unaired pilot, “The Cage”. She would later play the voice of the Starfleet computers and Lwaxana Troi on Star Trek: The Next Generation.
This is the first episode Spock uses the Vulcan Nerve Pinch, which he uses on Sulu.
When Spock sends Riley to Sickbay, he orders Uhura to take the Navigator position.
Star Trek: The Next Generation will pay homage to this episode in “The Naked Now”.

Original Airdate 10/6/1966

Story
Teleplay Richard Matheson
Director Leo Penin

Synopsis
While orbiting the planet Alpha 177, a transporter malfunction creates a duplicate of Kirk — one good and honorable, the other evil and aggressive. The Evil Kirk runs amok on his ship, committing violent acts, including the attempted assault of Yeoman Rand. As the two Kirks fight for control of the ship, Sulu and the landing party are stranded on the planet, its subfreezing night temperatures meaning certain death.

James Doohan (Lt. Cmdr. Montgomery Scott)

Story Gene Roddenberry
Teleplay Stephen Kandel
Director Harvey Hart

Synopsis
The Enterprise rescues con artist Harry Mudd and his beautiful female cargo. In pursuit of Mudd’s ship, the Enterprise has burned out its lithium crystals, which power the starship’s engines, and Kirk orders them to proceed as quickly as possible to the nearest lithium mining planet, Rigel XII. Mudd makes a deal with the three miners to deliver his three women to be their wives.

Jon Kowal (Herm Gossett)

Notes
Harry Mudd will later return in “I, Mudd”.
The women were “ugly”, made attractive by the illegal Venus drug. They revert to their former selves if they go off the drugs. However, when Eve goes off the drug, Kirk tricks her with a gelatin pill and she becomes pretty because she believes she is (which is well-meaning, but absolutely ludicrous).
For some unknown reason, Uhura is wearing a yellow uniform instead of her standard red uniform.

A landing party beams down and discovers that 300 years before, the natives of the planet conducted experiments to prolong life, but had instead created a deadly virus, which killed all adults by rapid aging and madness. In children, the virus slowed the natural aging process greatly, leaving them in a state of prepubescence for centuries.

“The Corbomite Maneuver”

Episode Number 10
The crew awaits the Fesarius’ response
Production Number 003
Season 1
Stardate 1512.2
Original Airdate 11/10/1966

Story
Teleplay Jerry Sohl
Director Joseph Sargent

Synopsis
While exploring an uncharted region of space, the U.S.S. Enterprise comes upon an alien space buoy, warning ships away and blocking the starship’s path. Kirk’s orders the phasers to destroy the buoy but immediately an alien ship, the I.S.S. Fesarius, shaped like a large, glowing crystal traps the starship. The Fesarius captain Balok tells Kirk that the Enterprise has trespassed and committed hostile actions, and therefore, must be destroyed. Employing a trick from the Earth game of poker, Kirk tries a desperate bluff by convincing Balok that if the Enterprise is fired upon, the “corbomite” in the starship’s hull will self-destruct and destroy both ships.

Guest Cast
Anthony Call (Lt. Dave Bailey)
Clint Howard (Balok)
DeForest Kelley (Dr. Leonard H. McCoy)
Grace Lee Whitney (Yeoman Janice Rand)
George Takei (Lt. Hikaru Sulu)
James Doohan (Lt. Cmdr. Montgomery Scott)
Nichelle Nichols (Lt. Uhura)

Notes
McCoy gives Kirk a physical and then puts him on a salad diet.
This episode moves along at a very slow pace; The Enterprise does not destroy the bouy until nearly halfway through the episode.
Bailey remains behind with Balok as part of an exchange program so that Balok can learn more about the Federation, at Kirk’s suggestion for a volunteer. Bailey seems an odd choice, since the stress of the [not very stressful] encounter rendered him unable to perform his duties.
Captain Kirk announces the ship as the United Earth Ship Enterprise.

Synopsis
Kirk is contacted by Dr. Leighton, a friend from the Tarsus IV colony years ago, who believes that Kodos the Executioner — the militant dictator who executed half of the people on the colony — is at large once more in the guise of touring Shakespearean actor Karidian.

Guest Cast
Arnold Moss (Anton Karidian)

Notes
Leighton, Kirk and Riley are the only remaining three (of only nine people) who actually saw Kodos. Spock discovers the other six all died when the Karidian Players were somewhere near. Riley’s parents were killed on Tarsus IV by Kodos.
Lenore is actually the killer. She killed Leighton, then tried to kill Riley.
When Lenore tries to kill Kirk with a phaser, Anton moves to protect him and she kills her father.
In the rec room, Uhura plays Spock’s lute and sings a song to Riley, who is bored and alone in the engine room.

The Romulan Commander
Production Number 009
Season 1

Original Airdate 12/15/1966

Story
Teleplay Paul Schneider
Director Vincent McEveety

Synopsis
Responding to distress calls from border outposts along the Neutral Zone between the Federation and the Romulan Star Empire, Kirk and the crew receives a final message from a Federation station reporting an attack from an invisible ship, now running at full speed towards home. The U.S.S. Enterprise pursues the warbird, hampered by the fact that the Romulans have constructed an invisibility screen which shields them from view. After every attempt to lose the Enterprise fails, the Romulan Commander is forced to turn and fight. Both ships are damaged and rather than let himself and his ship be taken prisoner, the Romulan Commander self-destructs the warbird.

Guest Cast
Mark Lenard (Romulan Commander)
Paul Comi (Lt. Andrew Stiles)
Lawrence Montaigne (Decius)
DeForest Kelley (Dr. Leonard H. McCoy)

James Doohan (Lt. Cmdr. Montgomery Scott)
Nichelle Nichols (Lt. Uhura)
Stephen Mines (Lt. Robert Tomlinson)
Barbara Baldavin (Specialist Angela Martine)
Garry Walberg (Commander Hansen)
John Warburton (Centurion)

Notes
This is the first appearance of the Romulans, who look very much like Vulcans. Spock deduces that they must be an offshoot of the Vulcans, from the time when they were aggressive and savage.
The Neutral Zone was established 100 years prior, after the Earth-Romulan War. They had never seen a Romulan until now.
The Federation built outposts along the Neutral Zone, constructed on asteroids.
The Captain was in the middle of a wedding ceremony between Tomlinson and Martine when the ship went to red alert. Tomlinson died during the attack.
Mark Lenard will later play Spock’s father Sarek in the episode “Journey to Babel”.
This is the last appearance of Janice Rand. She will return to the Enterprise in Star Trek: The Motion Picture. (Apparently, Grace Lee Whitney was assaulted on the studio lot by a Star Trek executive. She didn’t report the attack, but she was soon fired from the series.)

Story
Teleplay Theodore Sturgeon
Director Robert Sparr

Synopsis
A U.S.S. Enterprise landing party beams down to an uncharted planet. The planet seems like a perfect candidate for shore leave with its “Earth-type” characteristics. McCoy’s first encounter on the new world is with a life-sized white rabbit in a waistcoat, being chased by a little girl. Kirk beams down himself to find his old rival from his academy days, Finnegan. While trying to catch him, Kirk meets Ruth, an old girlfriend. Elsewhere, Sulu is attacked by a Samurai Warrior while others are chased by tigers and aircraft. As the perils become more and more deadly, Kirk and Spock realize that their thoughts are somehow coming to life around them.

Marcia Brown (Alice)
Sebastian Tom (Samurai Warrior)

Notes
Barbara Baldavin played Angela Martine in the previous episode, but was cast as Mary Teller in this episode. The mistake was discovered halfway through filming, which is why Kirk calls her “Teller” near the beginning and Rodriguez calls her “Angela” near the end.
Kirk’s shirt is ripped fighting with his annoying Finnegan.

Synopsis
On its way to deliver medical supplies to plague-ridden Makus III, the U.S.S. Enterprise passes Murasaki 312. Since they are under Starfleet orders to inspect galactic phenomena such as this quasar-like star group, Spock, McCoy, Scott and four specialists take the shuttlecraft Galileo for a closer look. Unexpectedly, the Galileo is pulled off course and crashes on the planet Taurus II in the center of the Murasake phenomenon. Between attacks by the giant, hostile inhabitants and quarrels among themselves, the crew attempts to repair the shuttle and get off the planet.

Notes
With a rank of [Lt.] Commander and many years in Starfleet, it seems odd that this is Spock’s first command mission, which he handles poorly until the end.

In an uncharted area of space, both the alien ship and the Enterprise are caught by an advanced race called Metrons. The Metrons are angry at the two ships for trespassing into their space and believe that physical combat is the answer to finding justice.

When the U.S.S. Enterprise is thrown into a time warp by a black star, it ends up orbiting Earth in the 20th century. A jet is dispatched to bring the “UFO” down and the plane is accidentally destroyed by the starship’s tractor beam, forcing Kirk to beam the pilot, John Christopher, aboard.

Guest Cast
Roger Perry (Capt. John Christopher)
DeForest Kelley (Dr. Leonard H. McCoy)

Notes
Kirk tells Christopher that there are 12 starships like Enterprise, under the authority of the United Earth Space Probe Agency.
Kirk introduces Spock to Christopher as his “First Officer, Lieutenant Commander Spock” though he clearly wears the uniform of a Commander.
The computer was upgraded on Cygnet XIV, a female dominated world. They gave the computer a sexy personality. It calls the Captain “dear”, speaks seductively, and has the annoying tendencies to giggle and pout. (Apparently, women can’t make professional computer systems!)

Director Marc Daniels

Synopsis
When the U.S.S. Enterprise puts in at Starbase 11 for repairs caused in an ion storm, Kirk gives his report of the circumstances of Lieutenant Commander Ben Finney’s death to Commodore Stone. All goes well until Spock arrives with the computer visual tape of the bridge during the crisis. Spock tries to warn Kirk about what is on the tape, but the Commodore takes it and plays it. The computer record shows that Kirk jettisoned the ion pod with Finney still inside.

Guest Cast
Percy Rodriguez (Commodore Stone)

Nancy Wong (Personnel Ensign)
Bart Conrad (Captain Krasnowsky)
William Meader (Commodore Lindstrom)
Reginald Lal Singh (Captain Chandra)

Notes
Finney and Kirk were friends at one time; Finney’s daughter Jamie was named after Kirk. They were stationed on the U.S.S. Republic NCC-1371 together. Then Ensign Kirk discovered that Lt. Finney had left open a switch on the atomic reactor, which could have caused an explosion. Kirk logged the incident and Finney was reprimanded and moved to the bottom of the promotion list. He never forgave Kirk. Finney was the Enterprise’s records officer. He changed the computer records and faked his death because he was bitter over never becoming Captain and commanding officer of the Enterprise.
The computer identifies Spock’s rank as Lieutenant Commander. (Kirk also referred to him as such in the previous episode “Tomorrow is Yesterday”.)
During “The Menagerie”, Kirk states that no starships can create detailed records such as the video playback provided by the Talosians. However, in this episode they have detailed records of the ion storm, which can even zoom into Kirk’s button presses.
Spock proves that there is something wrong with the computer because he is able to beat it at chess 4 times in a row.
Kirk states that the computer can hear sounds. Using a booster, they can increase it on the order of “one to the fourth power”. 14=1, which would render the sound the same.

Synopsis
The U.S.S. Enterprise is investigating Beta III, where the U.S.S. Archon disappeared over 100 years before. When the landing party exhibits strange behavior, Kirk sends another party down to investigate. They find the culture on Beta III is quiescent, with no creative tendencies. The entire culture, known as “The Body”, is controlled by a group of lawgivers, who are in turn controlled by the omniscient Landru.

Notes
In one of Star Trek: The Original Series’ recurring themes, the Beta III society is controlled by a computer, Landru. The computer was created by the real Landru 6000 years ago. Kirk convinces Landru that it is evil and it destroys itself.
Sociologist Lindstrom remains behind with a party of experts to help the Betans rebuild their culture.
Spock apparently is able to sleep with his eyes open.

Story Carey Wilber
Teleplay Gene L. Coon and Carey Wilber

Synopsis
The Enterprise discovers the S.S. Botany Bay, an old-style, pre-warp sleeper ship from Earth that contains several bodies in stasis. Amongst these bodies is Khan Noonien Singh, a genetically-engineered strongman and one of the great leaders of Earth’s Eugenics War of the 1990s. Once aboard the U.S.S. Enterprise, Khan quickly befriends the beautiful Lieutenant Marla McGivers, and together with his Botany Bay crew and new companion, they seize control of the Enterprise.

Guest Cast

John Winston (Lt. Kyle)

Notes
The S.S. Botany Bay is a DY100-class vessel built in the 1990s.
Khan and his crew are exiled to planet Ceti Alpha V where they must start life anew. Rather than face court martial, Marla McGivers chooses exile with Khan. (Female officers don’t seem to fare very well in The Original Series.)
Spock wonders what will become of the seed they have planted. These events become the background for the motion picture Star Trek II: The Wrath of Khan.

Story Robert Hamner
Teleplay Robert Hamner and Gene L. Coon
Director Joseph Pevney

Synopsis
The U.S.S. Enterprise is ordered to pick up Ambassador Robert Fox, who is headed to planet Eminiar VII on a diplomatic mission. Upon arriving at the planet, the ship is warned away because Eminiar is at war with Vendikar, the third planet in the Eminiar system. Beaming to the surface with a landing party, Kirk discovers that the war between the two planets is controlled by computers, which determine the damage done and the fatalities caused by the attacks, and assigns citizens to report to disintegration machines, which they do so willingly.

Guest Cast
David Opatoshu (First Councilman Anan 7)
Gene Lyons (Ambassador Robert Fox)
DeForest Kelley (Dr. Leonard H. McCoy)
James Doohan (Lt. Cmdr. Montgomery Scott)
Barbara Babcock (Mea 3)
Miko Mayama (Yeoman Tamura)
David L. Ross (Lt. Galloway)
Nichelle Nichols (Lt. Uhura)
Sean Kenney (Lt. DePaul)
Robert Sampson (Sar 6)

Notes
The last starship to visit Eminiar VII was the U.S.S. Valiant, over 50 years ago. The ship never returned from the mission.
The United Federation of Planets is mentioned for the first time in this episode.
Spock mentions for the first time that “Vulcanians” have telepathic ability, which he uses to control an Eminiaran guard, forcing him to open their locked door. (This seems to contradict the episode “Where No Man Has Gone Before”, where Mitchell and Dehner have the highest ESP ratings on the ship).
Ambassador Fox stays behind to mediate peace between Eminiar and Vendikar.
Kirk gives “General Order 24” to Scotty — the destruction of the planet’s inhabitable surface.
The Eminiar disrupters make a loud noise, but no visible beam.

Synopsis
The Enterprise arrives at Omicron Ceti III, hoping to find surviving colonists who have been exposed to deadly berthold rays for three years, and the crew is surprised to find the colony alive and flourishing. Spock beams to the surface and meets Leila Kalomi, a young botanist that he’d worked with previously, who also developed romantic feelings for him. Eager to keep Spock on Omicron Ceti, Leila leads the Vulcan to a secluded section of the planet where a native plant sprays him with their spores. Leila tells Spock that the plant induces feelings of harmony and peace and love, along with a desire to remain on Omicron Ceti III and their paradise.

Guest Cast
Jill Ireland (Leila Kalomi)
Frank Overton (Elias Sandoval)
DeForest Kelley (Dr. Leonard H. McCoy)
Grant Woods (Lt. Kelowitz)
George Takei (Lt. Hikaru Sulu)
Nichelle Nichols (Lt. Uhura)
Michael Barrier (Lt. Vincent DeSalle)
Dick Scotter (Painter)
Eddie Paskey (Lt. Lesley)

Notes
The spores thrive on berthold rays, which is why the colonists survived. Anger nullifies the effect of the spores.
After McCoy is overtaken by the spores, he develops an over-exaggerated Southern accent.
Leila first told Spock that she loved him 6 years ago; they apparently worked together on Earth at that time.

Synopsis
The U.S.S. Enterprise arrives to investigate reports of an unknown monster deep in the mining tunnels of Janus VI. The being is apparently destroying machinery and killing the miners, and has the ability to burrow through solid rock. Spock attempts a Vulcan mind meld with the entity and discovers that it is an intelligent being. A native of the planet, the Horta is normally peaceful and doesn’t mind sharing the planet with the miners, but when they broke into the Horta’s hatchery and unknowingly destroyed many of her eggs, it attacked to protect its remaining unborn children.

Barry Russo (Lt. Cmdr. Giotto)
James Doohan (Lt. Cmdr. Montgomery Scott)
Brad Weston (Ed Appel)

George E. Allen (Engineer)
Jon Cavett (Guard)

Notes
The Horta is a silicon-based creature. The silicon nodules the miners discovered were its eggs.
This is the first episode McCoy uses what will become his catch phrase, stating “I’m a doctor, not a brick-layer”.
The Horta looked like an over-sized plastic vomit.

Synopsis
While negotiations quickly break down between the Federation and the Klingon Empire, the Enterprise is sent to Organia, a planet of primitive people strategically located between the two sides. Kirk and Spock beam down in an attempt to convince the peaceful Organians to accept Federation aid and protection against the Klingons. When the Klingon forces attack the planet, the Enterprise and the Klingon forces square off to battle in orbit of the planet. Displeased by the outbreak of violence, the Organians reveal themselves to be powerful creatures of pure energy who easily neutralize the weapons on both ships, and force both sides to sign a peace treaty.

Story
Teleplay Don Ingalls
Director Gerd Oswald

Synopsis
Starfleet is baffled by a phenomenon and suspicious it’s a “rip in the universe.” It sends the Enterprise to check it out and what at first is thought to be a sign of attack is no less than the impact of one man. This man, Lazarus, veers wildly between calm and chaos as he pursues his single-minded mission. The puzzle becomes more baffling when he turns out to be “twins” — and his small downed spacecraft a gateway to another dimension.

Guest Cast

Synopsis
While treating Sulu on the bridge, McCoy accidentally injects himself with an overdose of cordrazine. In his cordrazine induced frenzy, McCoy exits the bridge and manages to beam himself down to the planet below. Kirk and the landing party are too late to stop the Doctor from leaping through a living time machine called “The Guardian of Forever.” At that moment, the Enterprise ceases to exist and the landing party is stranded. The Guardian explains that McCoy went back into Earth’s history and changed it, thereby altering the future. Kirk and Spock go through the Guardian, to Depression-era America, a few days before McCoy is to arrive and change history.

Guest Cast
Joan Collins (Sister Edith Keeler)
DeForest Kelley (Dr. Leonard H. McCoy)

Bartell La Rue (voice of The Guardian)

Notes
Even though Kirk falls in love with Edith Keeler, he must let her die to restore the timeline.
As soon as the Enterprise disappears, Uhura tells Kirk, “Captain, I’m frightened!”
To explain Spock’s ears, Kirk says that Spock is Chinese and he caught his ears in a mechanical rice picker. (Rather insensitive for such an enlightened century.)

Synopsis
Arriving at the planet Deneva, home of Kirk’s only brother Sam and his family, the U.S.S. Enterprise picks up a transmission from a Denevan pilot who has steered his craft into the sun to destroy some unknown menace. Beaming down to the planet, Kirk finds his brother dead and Sam’s wife and son in a fatal condition. Before Aurelan dies, she informs the landing party that Deneva has been infested with large, amoeba-like aliens that attack humans and intertwine their tentacles with the body’s nervous system, inflicting excruciating pain while forcing the victim to obey the entity.

Guest Cast
DeForest Kelley (Dr. Leonard H. McCoy)
James Doohan (Lt. Cmdr. Montgomery Scott)
Joan Swift (Aurelan Kirk)
Maurishka Taliferro (Yeoman Zahra)
Majel Barrett (Nurse Christine Chapel)
George Takei (Lt. Hikaru Sulu)
Nichelle Nichols (Lt. Uhura)
Craig Hundley (Peter Kirk)
Fred Carson (First Denevan)
Jerry Catron (Second Denevan)

Notes
The Deneva colony was colonized 100 years prior, a stop on the Earth Cargo Service run.
The Enterprise has 14 science labs, one of which is shown for the first time in this episode.
Bright light kills the creatures. McCoy used all light spectrums when testing the procedure on Spock, blinding him. Since Vulcans have an inner eyelid, Spock recovers from his blindness (naturally). 210 satellites are deployed around Deneva to bombard the planet with ultra-violet light.
William Shatner (sporting a moustache) also played the dead body of Sam Kirk.
When they first encounter the parasites, Yeoman Zahra says, “They don’t even look real.” She was right about that. Regardless, this episode is still a classic.

Synopsis
When Spock begins to exhibit strange, erratic behavior, Kirk asks McCoy to conduct a medical examination. McCoy concludes that Spock is experiencing a potentially lethal internal distress. Spock explains to them that Vulcans are married as children with the understanding that they will fulfill this commitment when they become adults. Spock has reached this time, the “pon farr,” and if he doesn’t get to Vulcan immediately to mate with his bride, T’Pring, he will die.

Starring
William Shatner (Captain James T. Kirk)

Lawrence Montaigne (Stonn)
Majel Barrett (Nurse Christine Chapel)
George Takei (Lt. Hikaru Sulu)
Nichelle Nichols (Lt. Uhura)
Walter Koenig (Ensign Pavel Chekov)
Byron Morrow (Admiral Komack)

Notes
The Vulcan T’Pau is to officiate Spock’s wedding. She is the only person to turn down a seat on the Federation council.
Instead of marrying Spock, T’Pring chooses the kal-if-fee (the challenge) and chooses Kirk to fight Spock to the death. Having defeated Kirk in the challenge, Spock’s pon farr is resolved and Spock allows T’Pring to wed Stonn.
This episode marks the first use of the Vulcan hand gesture and the phrase “Live long and prosper.”
This is the first appearance of Ensign Pavel Chekov, the new navigator.
Chief Engineer Lt. Cmdr. Scott does not appear in this episode, chosen to open Season 2.
DeForest Kelley (Dr. McCoy) becomes a regular cast member starting in Season 2 and his name now appears in the opening credits after Leonard Nimoy.
The theme song has added a female vocalizing the melody. The end credits version also has a slightly different instrumental arrangement.

Synopsis
As the U.S.S. Enterprise nears the planet Pollux IV, a huge, green hand made of energy materializes in space, catching the Enterprise and holding it captive. Kirk and a landing party are transported to the planet’s surface where they find a being who claims to be Apollo, the last of the Greek gods who dwelled on ancient Earth’s Mount Olympus.

James Doohan (Lt. Cmdr. Montgomery Scott)
George Takei (Lt. Hikaru Sulu)
Nichelle Nichols (Lt. Uhura)
Walter Koenig (Ensign Pavel Chekov)
John Winston (Lt. Kyle)

Notes
Scott has romantic interests in Carolyn Palamas. Apollo charms her, calls her beautiful, and she instantly falls in love with him, naturally. When Scott tries to step in, Apollo shocks him and throws him down. (Carolyn is too happy to have new clothes and a new boyfriend to care.)
Kirk suggests that perhaps Apollo and his kind did travel to Earth 5000 years ago to be worshipped as gods. Apollo could by lying, but it is never verified.
Uhura rewires the communication system circuit boards, enabling the Enterprise to contact the landing party.

Synopsis
The U.S.S. Enterprise is sent to investigate the destruction of the Malurian system and its four billion inhabitants. When it arrives at the coordinates, the starship itself is threatened by a space going, self-contained computer/probe calling itself Nomad. When Kirk identifies himself by name, Nomad mistakes him for “The Kirk,” and thinks him to be his creator.

Guest Cast

Majel Barrett (Nurse Christine Chapel)
Blaisdell Makee (Lt. Singh)
Barbara Gates (Astrochemist)
Meade Martin (Engineer)
Arnold Lessing (Lt. Carlisle)
Vic Perrin (Nomad’s Voice)

Notes
Nomad was created by scientist Jackson Roykirk in the early 2000’s. Nomad’s program was to seek out new life and report back to Earth. Spock melds with Nomad and discovers that it was damaged and it merged with an alien probe, changing its mission to erradicate imperfect biological lifeforms. (How is Spock able to mind-meld with a machine?)
Kirk convinces Nomad that it is imperfect and it self-destructs (see also “The Return of the Archons”).
Nomad erases Uhura’s memory and she must “relearn” what the probe erased. Nomad also kills Scott, but is able to “repair” him.
The story for this episode will be recycled for Star Trek: The Motion Picture.

Synopsis
When a landing party beams down to the planet Gamma Trianguli VI, they find what appears to be an idyllic paradise. They quickly discover, however, that the planet is deadly, sporting plants that shoot thorns, rocks that explode, and incredibly accurate lightning bolts. They encounter the planet’s inhabitants, a peaceful, child-like people who call themselves the “Feeders of Vaal.” Vaal seems to be a large serpent’s head carved of rock, but is actually the terminal for an advanced, underground computer.

Notes
Kirk and Scott don’t seem overly concerned for the first dead “red-shirt” security officer. After Kirk reports the death, Scott says that he heard it’s nice down on the planet and would love to come down to walk around! By the end of the episode, all four security red-shirts are dead.
Spock notes that destroying Vaal would violate the Prime Directive. Kirk ignores him.
Curiously, the tropical climate of Gamma Trianguli VI reminds Chekov of his home country, Russia.

Synopsis
Sent to investigate the destruction of several planetary systems, the U.S.S. Enterprise discovers the U.S.S. Constellation adrift in space. The only survivor, Commodore Matt Decker, informs the crew that a giant planet-eating machine made by a long-dead alien race is roaming the galaxy, consuming all in its path for fuel, including whole planets. Trapped on the derelict Constellation, Kirk can only stand by and watch as Decker takes command of the Enterprise, bent on seeking revenge against the planet killer.

John Copage (Crewman Elliot)
Tim Burns (Crewman Russ)
Jerry Catron (Ensign Montgomery)

Notes
The U.S.S. Constellation NCC-1017 is the first Federation starship to appear on screen, other than the Enterprise. (The ship model was a plastic toy model kit by AMT, which looked very cheap when the ship was entering the planet killer.)
A shuttle launch is seen for the first time in this episode.
Uhura does not appear in this episode; Lt. Palmer takes her place at communications.
A preview of the new Main Engineering set is seen as the U.S.S. Constellation’s engineering set. This new set will be seen in “I, Mudd”. (Curiously, after Scott gets the Constellation running, he is seen thrown around on the old Enterprise Engineering set.)
McCoy states that he is a “doctor, not a mechanic.”

Notes
DeSalle is now the Assistant Chief Engineer. Kirk puts him in charge of the Enterprise while they are on the surface.
Thankfully, this is the only Halloween episode produced for any Star Trek series.
James Doohan lost his right middle finger during WWII. Most of his scenes are shot to hide it, however, it is very noticeable in this episode.

Synopsis
The U.S.S. Enterprise is appointed to transport ambassadors from many worlds to the Babel Conferences. Among those aboard are Spock’s parents: Ambassador Sarek of Vulcan and his human wife, Amanda. At a cocktail party, Tellarite Ambassador Gav quarrels openly with Sarek about the admission of Coridan into the Federation. When Gav is later murdered, circumstantial evidence points to Sarek. Meanwhile, an unknown vessel is following the Enterprise.

Guest Cast

Notes
Mark Lenard previously played the Romulan commander in “Balance of Terror”.
This episode introduces the Andorian and the Tellarite species. Along with Humans and Vulcans, they are the two other founding members of the United Federation of Planets. The Andorians are blue-skinned with two antennae on top of their heads. The Tellarites are pink pig creatures.
Spock and Sarek haven’t spoken in 18 years over Spock’s decision to join Starfleet instead of the Vulcan Science Academy.
Vulcans show “affection” by touching their index and middle fingers to each other.
Thelev was surgically altered to appear Andorian. Spock deduces that he is an Orion. The Orions wanted to block Coridan’s admittance into the Federation so that they could continue to steal their dilithium and sell it for profit.

Synopsis
Sent to the planet Capella IV to negotiate a mining treaty with the warlike and tradition-bound people, Kirk and a party beam to the surface. Kirk finds that Klingon agent Kras has also arrived to negotiate a mining treaty with the Klingon Empire. Kirk and Kras negotiate with Teer Akaar, the leader of the tribes of Capella. Akaar favors the Federation while Maab, a highly influential Capellan, favors the Klingons. During a factional fight, Akaar is killed and Maab is installed as the new tribal leader. The landing party is imprisoned with Eleen, the pregnant widow of Akaar, and she prepares to be put to death according to custom.

McCoy: “I’m a doctor, not an escalator.”
Eleen becomes Regent of Capella until her child, named Leonard James Akaar, can take over as Teer (leader).
The Capellan double-vowels are prounced separately (e.g., Aka-Ar, Elee-En).

Production Number 041
Season 2
Stardate 3478.2
Original Airdate 12/8/1967

Story
Teleplay David P. Harmon
Director Joseph Pevney

Synopsis
On the way to Starbase 10, the U.S.S. Enterprise stops to deliver supplies to the 6 colonists of Gamma Hydra IV. A landing party consisting of Kirk, Spock, McCoy, Scott, Galway and Chekov beams to the planet’s surface and finds that accelerated aging has taken place, killing most of the colonists. The only two survivors, an elderly couple who claim to be in their twenties, die shortly after meeting the Enterprise crew. When the landing party returns to the Enterprise, the aging acceleration begins to affect each of them… except Chekov, who remains curiously immune.

Guest Cast
Charles Drake (Commodore George Stocker)
Sarah Marshall (Dr. Janet Wallace)
James Doohan (Lt. Cmdr. Montgomery Scott)
George Takei (Lt. Hikaru Sulu)
Nichelle Nichols (Lt. Uhura)
Majel Barrett (Nurse Christine Chapel)
Walter Koenig (Ensign Pavel Chekov)
Felix Locher (Robert Johnson)
Carolyn Nelson (Yeoman Doris Atkins)
Laura Wood (Elaine Johnson)
Beverly Washburn (Lt. Arlene Galway)

Notes
Stocker orders the ship to Starbase 10, crossing the Neutral Zone, where the Enterprise is attacked by Romulans. Stocker falls apart, but a healthy Kirk saves the day by using the “The Corbomite Maneuver”.
A competency hearing is called to relieve Kirk of duty. In the later series, the chief medical officer can relieve the captain if he is unfit without holding a hearing. (The sequence is rather lengthy and brings the already poorly-paced story to a halt.)
Chekov was immune because he was scared when he found the dead body; the adrenaline kept him from aging. Lt. Galway died fairly quickly.
Like many of the female guest stars, Dr. Janet Wallace once had a love affair with Kirk. When they broke up, she married Theodore Wallace, who was 26 years older than her and died recently. After Kirk started aging, Janet realized she still loved Kirk.
Kirk states that he is 34 years old.

Synopsis
Eleven years ago, the U.S.S. Farragut encountered a deadly cloud creature with vampire-like tendencies. James T. Kirk was on board the Farragut at that time as they entered the region of Tycho IV. The creature killed the ship’s commander, Captain Garrovick, and half the crew by draining their red blood cells. On his way to deliver necessary medical supplies, Kirk encounters what he believes is the same blood-sucking entity. He pursues it, against orders, determined to destroy it before it kills again.

Notes
Kirk previously served as a lieutenant on the starship U.S.S. Farragut NCC-1647.
Vulcan blood is copper based, not iron as with humans. This gives it a green color.

Story
Teleplay Robert Bloch
Director Joseph Pevney

Synopsis
Kirk and McCoy decide to take Scotty, who is recovering from a head wound accidentally caused by a female crew member, to a nightclub on the planet Argelius II. Scotty becomes infatuated with a lovely dancer at the club and they leave together. In the meantime, Kirk and McCoy decide to sample some of the planet’s other pleasures and leave. A scream sends them to a foggy alley to find the dancer dead with Scotty holding a bloody knife.

Guest Cast

Joseph Bernard (Tark)
Tania Lemani (Kara)
John Winston (Lt. Kyle)
Virginia Aldridge (Lt. Karen Tracy)
Judith McConnell (Yeoman Tankris)
Judi Sherven (Nurse)

Notes
Kirk and McCoy took Scott to Argelius because he was suffering from “total resentment of women” because a woman caused his concussion.
The murderer, inhabiting Hengist’s body, is an alien creature known as Redjack a/k/a Jack the Ripper. The alien consumes the emotion of fear, killing women because they frighten more easily.
John Fiedler was an odd choice for Hengist, who seemed too wimpy and goofy to be inhabited by a serial killing alien. (Fiedler is known for his role on “The Bob Newhart Show” and has been the voice of Pooh’s little friend Piglet since 1968.)
Spock used the transporter to disperse Hengist’s body and the creature into space.
Scott’s home town is Aberdeen, Scotland, UK.
The close-up shots of Scott’s hand on the computer witness stand are not of James Doohan’s hand. (He is missing a finger on that hand.)

Enterprise receives a top-priority order to protect a shipment of quadrotriticale grain on Deep Space Station K-7, Kirk is irritated to be guarding a shipment of “wheat.” With Klingons taking shore leave on the space station, Federation Undersecretary for Agriculture Nilz Baris and his pesty assistant Arne Darvin inform Kirk that Starfleet Command is afraid the Klingons may try to steal the grain. Meanwhile, space trader Cyrano Jones gives Uhura a purring ball of fluff known as a tribble. Charmed by the cute creature, Uhura takes it back to the Enterprise, where it multiplies and the starship is soon overrun by the furry creatures.

When the landing party beams down, Spock is seriously injured and is returned to the Enterprise for treatment as Kirk and McCoy try to make contact with the locals.

The Enterprise pursues the woman’s ship to the Sigma Draconis IV system. When Kirk and party beam down, they find a rough, frozen world inhabited by two peoples: the Morgs, primitive men who live on the surface, and the Eymorgs, females who live deep underground in a comfortable, highly technological city, yet have primitive, child-like minds.

Synopsis
Seeming tense and erratic, Captain Kirk takes the U.S.S. Enterprise into Romulan space and the ship is immediately surrounded by Romulan warships. Kirk and Spock beam aboard the Romulan flag-ship and confront the Romulan Commander. Kirk explains that his ship entered Romulan territory because of equipment malfunction. Spock denounces this explanation, saying Kirk ordered them here due to his reduced mental stability. Kirk attacks Spock, who returns the attack using the Vulcan death grip, killing Kirk. Kirk’s body is returned to the Enterprise while Spock remains on the Romulan ship. Unknown to the Romulan Commander, this has all been a ploy to sneak the officers on board and steal the Romulan cloaking device. Disguised as a Romulan, Kirk returns to the Romulan ship and steals the vessel’s cloaking device and returns with it to the Enterprise.

The United Federation of Planets sends the U.S.S. Enterprise to Gideon, in the hope that the Gideons will become a member. The planet Gideon appears to be a haven — the inhabitants are healthy and no one seems to ever die in the totally germ-free environment. Reluctantly, the Gideon council allows Captain Kirk alone to beam to their council chamber, and he transports off the ship. Kirk finds himself on his own ship, where all of his crew have seemingly vanished, except for a Gideon woman, Odona. Kirk realizes that the ship is fake, and when Odona becomes ill, the Gideons’ plan is revealed: using Kirk’s blood, Odona was infected with a disease which Kirk had recovered from. The infection is fatal, and the Gideons hoped to spread it across their world to reduce the population.

Notes
NBC cancelled Star Trek, making this the series finale.
This episode was originally to air in March 1969, but was pre-empted due to the death of President Eisenhower.
Not allowing females to captain starships seems very un-Starfleet.
Christine Chapel appears as a brunette in this episode. Majel Barrett also played Number One in the unaired pilot, who was also a brunette.
Lt. Uhura was the only series regular to not appear in the final episode.
