Something Awful members write summaries of Backward Films:

Star Trek II: Khan of Wrath The

To their astonishment, the crew of a heavily-damaged USS Enterprise discover Spock’s dead body in a torpedo casing on the surface of a strange, newly-formed planet near the Mutara Nebula. They recover the body, which happily comes back to life, so McCoy restores Spock’s “katra” and heals his horrible wounds by exposing him to the life-giving radiation of the warp core.

MeFi adds a few of its own suggestions. Too bad none of these will ever be actual movies.
