Star Trek: The Search for Spock

Star Trek: The Search for Spock is the third movie of the Star Trek movies. Based right after the events of the second movie Star Trek: The Wrath of Khan, the movie shows the Enterprise limping home and its crew saddened with the loss of Spock.

Apparently, Spock isn't dead after all. Spock's body regenerated on the Genesis planet and Spock's mind was stored in the mind of Dr. Leonard McCoy. Kirk needed his ship back to go save his friend, and while Starfleet, Klingons, and a skeleton crew got in his way, Kirk does manage to find Spock's body and return him to Vulcan for the rejoining of mind and body.
