Captain Kirk, Mr. Spock, Dr. McCoy, Scotty, and Chekov are forced to re-enact the gunfight at the O.K. Corral in Tombstone as the team that lost the gunfight.



On a mission on behalf of the Federation to establish contact with the reclusive and xenophobic Melkotians, Captain Kirk decides to ignore the message of a space buoy warning the USS Enterprise to immediately withdraw from Melkotian space and go back the way it came. Kirk hears the warning in English, but Spock, Chekov and Uhura hear it in Vulcan, Russian, and Swahili; their respective native languages. This leads the crew to deduce the message was transmitted telepathically. Kirk orders Uhura to further contact the Melkotians, but there is no response.

When Spock, Kirk, Scott, Dr. McCoy, and Ensign Chekov beam down to the Melkotian planet, they materialize in a fog bank not recorded by sensors. Their tricorders and communicators do not function. The landing party encounters a Melkotian. The Melkotian emerges from the fog and tells the Enterprise officers that their warning was plain, they have disregarded it, and will now be punished.

Act One[]

The Melkotian informs them that they are "outside" – a disease that must be destroyed. They learn that their trespassing is to be punished by death and how they will die will be taken from Kirk's mind, since it was he who ordered that the Melkotians' warning be disregarded. The Malkotian tells Kirk that "yours shall be the pattern of your death."

The landing party suddenly finds itself teleported to a facade of a 19th century American frontier town, albeit one with a dark red sky. All of their Starfleet equipment is gone, and instead each now has an Old West-style gunbelt and revolver. They observe the curious "incompleteness" of the town: buildings with only a front wall, with others open to the air on the sides and back; as well as signs and clocks strangely hanging in mid-air. (In fact, the town looks similar to a set one would see in either a 20th century movie or a theater play.) Kirk reads from a copy of the Tombstone Epitaph, a newspaper with the date of October 26th, 1881. Kirk wonders "Why here? And why now?" Spock notes that the time and place is based on the patterns of Kirk's memories. A man with a sheriff's badge greets them, acting as though he knew them well. He refers to Kirk as Ike, Spock as Frank, Scott as Billy, and McCoy as Tom. Recognizing the sheriff's name, Johnny Behan, Kirk quickly puts the names together. Ike Clanton, Frank McLowery, Tom McLowery, William Claiborne and Billy Clanton. He further recalls that the Clantons were one of the factions who fought for control of the town of Tombstone; the other being the Earps: Wyatt, Morgan, and Virgil, who were the town marshals, as well as "Doc" Holliday. Spock notes that the famous gunfight of the O.K. Corral took place on October 26, 1881 and that the Clantons lost. Kirk warns that the antique guns they all are carrying can be as deadly as phasers at close range.

They witness the shooting of a bar patron by Morgan Earp, and conclude that death is one thing that is real in this surreal scenario. Inside the bar, Chekov is accosted by a woman named Sylvia who claims to know him as Billy. Kirk recognizes Morgan as the man who kills on sight, and rises to confront him. Spock cautions him to back down, without moving a muscle, as he would be quickly gunned down in a "fast draw." Kirk says he does not want any trouble from Earp, but Earp says he will get them to draw soon enough, and then leaves.

Kirk and Spock discuss what is expected to happen based on history, that they are supposed to be killed at the OK Corral at 5:00 p.m. Kirk says that they will not be there. Kirk tries to convince Ed the bartender vehemently that he is not Ike Clanton, that he and his group are from the future, Kirk is the captain of a starship, but to no avail. The bartender tells him it makes no difference who he thinks he is, but rather whom the Earps think he is, while walking away still laughing.

Kirk then attempts to make peace with the Earps, saying there is a mistake. Virgil Earp says that he always felt the Clantons were "yellow" and then hits Kirk. Kirk strikes him back, Wyatt Earp then draws on Kirk, but Virgil stops him. Wyatt Earp warns Kirk that if he is in town at 5:01 p.m., the Earps will kill them.

Act Two[]

Kirk returns to the bar, and discusses what options they have with Spock, McCoy and Scotty. Kirk and the landing party try to leave town, but they are stopped by a force field. Spock notes that the Melkotians will not allow them to leave. Recognizing that they must fight, Kirk asks if they can find some way to stop the Earps using materials at hand in this recreation of Tombstone. McCoy and Spock cooperate to build a tranquilizer gas grenade which will incapacitate the Earps. McCoy encounters the town dentist, "Doc" Holliday, while acquiring the chemicals needed for the tranquilizer, asking to borrow a small quantity for a serious emergency. Holliday tells McCoy that his "emergency sure is real", and lets him take the chemical, but warns him to be finished by 5:00 p.m., because at "one minute past five, you'll find a hole in your head". Holliday then points his gun at McCoy to confirm this.

Meanwhile, Chekov has fallen in love with Sylvia, telling her outside the general store that he is looking forward eagerly to the dance next week. Sylvia asks if they can turn the dance into a wedding ball, but Chekov says that would not be possible, because he is not someone she could marry. The two share a passionate kiss, but then Morgan Earp appears and knocks Chekov down, and starts to walk Sylvia away. When Chekov gets up and shouts at Morgan to get his hands off Sylvia, Chekov draws for his gun, then is shot and killed by Morgan. Sylvia screams, which alerts Kirk, Spock, McCoy, and Scotty. They come out onto the street, as do the Earps. McCoy examines Chekov and tells Kirk that there is nothing he can do. Wyatt tells Kirk to "Do it now," and Scotty says that they must do something. Kirk however says that it's not yet time and they are not prepared.

Act Three[]

Back in the bar, McCoy and Spock work on the gas grenade. McCoy and Scotty give Spock a hard time for not showing any feelings over Chekov's death, as Scotty points out, he and Chekov worked closely together on the Enterprise. Kirk asks the two of them to stop but Spock notes that they forget he is half-Human. Spock observes that Chekov as Billy Claiborne died, but in the actual gunfight at the O.K. Corral, Billy survived. Kirk takes it to mean that the outcome of the conflict does not necessarily correspond with the historical outcome.

Kirk finds the sheriff and asks him to stop the fight, but Behan says that no one wants to stop the fight, and that it is a little late for Kirk to decide he "does not have the belly" for it. The sheriff tells Kirk that the people in the town are counting on Kirk to get rid of the Earps for them, and that no one would deny them their revenge for killing Billy. Kirk angrily says they just can't just kill them, but the sheriff says that there will be no questions asked as Kirk puts his hands around his neck. Upon seeing he will get no help from the sheriff, Kirk walks away.

With time running out, Scotty volunteers to test McCoy and Spock's gas grenade. Despite McCoy and Spock's careful preparation, it does not work — even when Scotty deeply inhales it. Spock finally realizes that nothing around them is real and that the entire scenario has been taking place in their minds.

Kirk vows they will not leave the bar until "well after 5 o'clock", but suddenly finds himself and the others teleported to the O.K. Corral where they cannot leave either, as it is surrounded by force fields.

Act Four[]

The corral is encircled by a force field so that escape is impossible. Spock, realizing this situation is only as real as their minds accept it to be, tries to convince the others that if they recognize that the situation is not real, they will not die and Kirk observes that the "smallest doubt" would be enough to kill them, just as it had killed Chekov. McCoy argues that they don't have that "clockwork ticker" in their heads like Spock, that they can't just turn it off and on at will. Kirk says that they must. Using a mind meld, Spock is able to convince everyone else that the bullets are not real, they are merely "shadows" and "illusions"; and "spectres without body… to be ignored."

The Earps arrive and demand that the ersatz Clantons draw, but the landing party refuses. The Earps begin shooting when Kirk reaches for his gun, but the bullets harmlessly pass right through the landing party, hitting the fence behind them. When the Earps deplete their ammunition, Kirk attacks Wyatt Earp and knocks him to the ground. Kirk draws his gun, and is about to shoot him, but upon seeing the abject terror in Wyatt's eyes, he releases him. The Earps then all fade and vanish.

Suddenly, the landing party finds themselves back on the bridge of the Enterprise. Chekov is alive and well, sitting at his station, and wonders "Where have I been?" Kirk suggests they have been on the bridge the whole time, and that Chekov survived because the only thing that was real to him was the girl. The Melkotian buoy once again appears on the main viewscreen directly in front of them, begins to emit M-rays beyond measurable levels, and then explodes. A Melkotian then appears on the viewscreen, noting that Kirk did not kill. Kirk explains that they fight only when there is no choice, and prefer peaceful contact. The Melkotian is silent for a moment, as if considering Kirk's explanation, then extends an invitation to establish relations with the Federation – asking Kirk to send a delegation to the planet.

Spock then asks Kirk a "personal" question: did he actually want to kill the Earps? Kirk agrees that is exactly how it was that afternoon, and how it was in 1881. Spock wonders how Humanity managed to survive. Kirk says that Humans overcame their instinct for violence, receiving a doubting look from Spock as he moves back to his console. The Enterprise then begins its orbit of Melkot.

Background information[]

Story and script[]

  • The story outline titled "The Last Gunfight" was dated 18 March 1968 and submitted 22 March 1968. The outline was retyped and dated to 19 April 1968 and submitted to NBC for approval on 22 April 1968 by Fred Freiberger.[1] The revised final draft was dated 14 May 1968, and filmed in late May.
  • James Blish's adaptation in Star Trek 3 has the title as "The Last Gunfight". Among the differences in the adaptation, the tranquilizer is delivered via darts; whereas in the episode, it is in the form of a nerve gas.
  • The writing of this episode was influenced by a series of memos which were sent between Gene Roddenberry and the executives at NBC, by the end of the second season, and which proposed that Chekov be featured in the third season more than he had been, up to that point. (Cinefantastique, Vol. 22, No. 5, p. 40)
  • The episode originally aired only one day before the 87th anniversary of the original gunfight at the O.K. Corral.


  • Clocking in at approximately five minutes and 25 seconds, this episode's teaser is the second longest in the original series, lasting 10 seconds shorter than the teaser for "I, Mudd".
  • This was the first episode produced for season three. As such, it was the first episode produced to feature blue text, rather than the yellow of the first two seasons, in the opening credits sequence.
  • A very subtle change in the third season was the use of new sound effects for the pushing of buttons on the bridge.
  • Another difference this episode brings is the "singing plant" background noise from "The Cage", used for nearly every planet in seasons one and two, is replaced here by a warbly sound used before on the planet Triskelion. This will again be used intermittently throughout season three – for example, in "For the World is Hollow and I Have Touched the Sky" and "The Cloud Minders".
  • Jerry Fielding's unique score adds atmosphere to this episode. When the villains are first seen in the saloon, Fielding has the piano play stereotypical "menace" notes and a bizarre rendition of "Buffalo Gals". Fielding's other Star Trek contribution was his score for "The Trouble with Tribbles".
  • A short clip in the third season blooper reel shows the Melkotian head wearing a fake mustache and horn-rimmed glasses. (Star Trek: Lost Scenes) Writing in an issue of the fan magazine Enterprise Incidents, James Van Hise said that the glasses belonged to co-producer Robert H. Justman.

Sets and props[]

  • The original script specified filming the episode on location in an outdoor Western town. However, due to budget restrictions, filming was confined to the regular studio stages. To avoid having to build a complete Western town set, the concept of an incomplete town, put together from "bits and pieces" out of Kirk's mind, was developed — therefore allowing the episode to be filmed within budget. (The Star Trek Compendium; Inside Star Trek: The Real Story, p. 403)
  • This is TOS's only foray into surrealism, with unique set designs by Matt Jefferies.
  • The sign that says SHERIFF has an identical font to the show's main titles. [2]
  • Mike Minor was the designer of the Melkotian's mask.

Cast and characters[]


  • This is one of three episodes that confirm Uhura's native language of Swahili (the other two being "The Man Trap" and "The Changeling").
  • This is the second time that McCoy believes he cannot be harmed by a weapon (this time due to Spock's convincing in a meld); the first time, when he stands his ground as the Black Knight charges him in "Shore Leave", this strategy was unsuccessful, as the weapon (a lance) was physically real, not merely an illusion.
  • This is the only episode to end with the Enterprise heading toward a planet rather than heading off into space.
  • Star Trek characters revisited the Old West in TNG: "A Fistful of Datas". That episode used outdoor sets, something the Original Series episode was unable to achieve due to budget constraints.
