When last we left the crew of the star ship Enterprise, they were heading home following a skirmish with the despotic Khan. Admiral Kirk and his bridge crew risk their careers stealing the decommissioned Enterprise to return to the restricted Genesis planet to recover Spock\'s body. It now becomes necessary to search for Spock\'s body, so that flesh and soul can be rejoined on Vulcan. It turns out that Spock\'s spirit is residing within the mind of the Vulcan\'s longtime shipmate, \"Bones\" McCoy.
