The Paradise Syndrome
"The Paradise Syndrome" is the third episode of the third season of the American science fiction television series  Star Trek. Written by Margaret Armen and directed by Jud Taylor, it was first broadcast October 4, 1968.
In the episode, an alien device on a primitive planet erases Captain Kirk's memory, and he begins a new life with the planet's indigenous people modeled on Native Americans.

Plot
Captain Kirk, First Officer Spock and Chief Medical Officer Dr. McCoy transport to the surface of an Earth-like planet, from which they are to deflect an approaching asteroid. They discover an obelisk with strange markings, and observe a settlement whose inhabitants, according to Spock, are descended from Native Americans (Mohican, Navaho and Delaware). Kirk, while out of sight of the others, falls through a trap door into the obelisk, where a beam shocks him into unconsciousness. Spock and McCoy are unable to locate Kirk and return to the Federation starship USS Enterprise to complete their mission.
Kirk awakens with amnesia, and a pair of women, including Miramanee, the tribal priestess, see Kirk emerge from their "temple." He is hailed as a god, and taken back to their village, where the tribal elders demand proof of Kirk's divinity. At that moment, a drowned boy is brought in. Salish, the medicine chief, declares the child dead, but Kirk uses mouth-to-mouth resuscitation to revive him. The elders accept Kirk as a god, forcing Salish to relinquish his position to Kirk.
In the meantime Spock, taking command of the Enterprise, drives her at maximum warp speed to beat the approaching asteroid to the deflection point. However, having pushed the engines well beyond their normal limits, there is not much energy left to deflect the asteroid. The ship's deflectors result in a change of only 0.0013 degrees in its course, which Mr. Sulu tells Spock is insufficient to avert collision with the planet. An attempt to cleave the asteroid like a diamond using the ship's phasers fails, and the attempt damages the warp drive beyond Scotty's ability to repair. Having exhausted their options, the Enterprise heads back to the planet on impulse power to attempt to recover Captain Kirk and devise another solution to the asteroid problem. The trip will take 59 days and according to Mr. Spock, "that asteroid will be four hours behind us all the way."
Following the tradition that the tribe priestess and medicine chief marry, Miramanee rejects Salish for Kirk.  Kirk falls deeper in love with Miramanee, though haunted at night by dreams of people he feels he should be with. Miramanee happily tells Kirk that she is pregnant.
As the Enterprise nears the planet, Spock succeeds in partially deciphering the markings on the obelisk. It is an asteroid deflector built by the "Preservers", an ancient race that resettled various endangered humanoid populations on other planets in order to ensure their survival. Spock surmises that the deflector has malfunctioned.
As the asteroid nears the planet, the sky darkens, thunder roars, and strong winds blow. The elders tell Kirk he must go into the temple to stop the storm. As Kirk pounds fruitlessly on the side of the obelisk, demanding that it open for him, the tribe turns against him. They begin stoning him and Miramanee. Spock and McCoy materialize, frightening the villagers away. Spock uses a mind meld to retrieve Kirk's memories, while McCoy tends to Miramanee's wounds. Kirk is able to open the trap door into the "temple" by speaking the correct tones to open it, and Spock activates the deflector with minutes to spare. McCoy tells Kirk that Miramanee will not survive. She dies in his arms, and he grieves.
