Episode Title: "SPECTRE OF THE GUN"
Production Number: 56
Original Air Date: 10-25-68
The U.S.S. Enterprise encounters a probe warning the ship to stay away from the space of the Melkot; the telepathic warning is heard in the native language of each Enterprise crew member. The Enterprise is under orders to establish contact with the reclusive Melkotians at all costs, so Captain Kirk orders a course farther into Melkot space.
Kirk leads a landing party to the Melkotian planet, but they find themselves trapped in a foggy environment. A Melkotian says they will be punished for disregarding the warning, and they find themselves in an incomplete simulation of Tombstone, Arizona, on October 26, 1881, the day of the gun fight at the O K Corral, and according to history, the landing party -- in the roles of the Clanton gang -- is destined to be killed by the Earps.
Spock realizes that the simulation is just a mental illusion created by the Melkotians, and is sure the bullets cannot harm him; he performs Vulcan mind melds with the other members of the landing party so they all share his certainty that the illusion cannot hurt them. Once the landing party survives the shootout without killing the Earps, they find themselves back on the Bridge of the Enterprise where they encountered the Melkot probe.
Since the Enterprise crew has proven itself peaceful, the Melkotians invite the crew to their planet to discuss an alliance.
Factoid: Spock's native language is Vulcan; Uhura's is Swahili; Chekov's is Russian; Kirk's is English.
