Star Trek III: The Search for Spock (Blu-ray)

Admiral Kirk's defeat of Khan and the creation of the Genesis planet, are empty victories. Spock is dead and McCoy is inexplicably being driven insane. Then a visit from Spock's father provides a startling revelation: McCoy is harbouring Spock's living essence. Kirk attempts to steal the U.S.S. Enterprise and defy Starfleet's Genesis planet quarantine to search for his friend, but the Klingons are planning a deadly rendezvous.
