Star Trek 3: The Search For Spock

Returning from his battle with Khan (see Star Trek 2: The Wrath Of Khan), Kirk (Shatner) is confronted by Spock's Father, demanding to know why he did not take Spock's body to Vulcan after the battle. Apparently, Spock's body died, but he would have placed his katra, or soul, in another person.

This person turned out to be McCoy (Kelley), who since the event has been acting kinda strange - well who wouldn't. Determined to return to the genesis planet and collect Spock's body, Kirk once again breaks just about every rule in the book, steals the Enterprise and along with the rest of the crew high-tail's it to the now-quarrantined Genesis.

Meanwhile, a Klingon captain named Kruge (Lloyd) learns of genesis. He views it as a terrible weapon and vows to learn it's secrets. He sets course for the planet also. On arrival, they destroy an orbiting Starfleet vessel, leaving Lt Saavik, a vulcan and Dr David Marcus, Kirk's son, stranded on the surface. They beamed down to search for life-signs and found a yound Vulcan boy, who turned out to be formed from Spock's reanimated cells and DNA.

By the time Kirk arrives, the Klingons have taken the three prisoner on the surface. Tricking the Klingons into believing he was surrendering, Kirk sets the auto-destruct sequence and beams off the ship just as the Klingons board.

Down on the planet, Kruge kills David in a fit of rage when he can't get the Genesis plans. Then the rest of the crew all beam up to the near-deserted Klingon ship, leaving Kirk and Kruge to fight to the death on a planet that is rapidly self-destructing. Will Kirk win? Will they get Spock back to Vulcan in time? Of course, because you all know there were at least six more movies to come!
