A “Star Trek” cast member steps into the role of director for the first time as Leonard Nimoy calls the shots on “Star Trek III: The Search For Spock,” the second chapter of a three-film story arc that began with “Star Trek II: The Wrath of Khan.” After the battle with Khan that resulted in the creation of a new planet via the terraforming Genesis Device (and the death of Spock), Dr. McCoy’s (DeForest Kelley) behavior becomes increasingly bizarre and aggressive due to him being the host of the fallen Vulcan’s katra, or life spirit. Kirk (William Shatner) is confronted by Spock’s father, Sarek (Mark Lenard), and told that Spock’s body and katra must be reunited in order to lay him to rest on his home world, prompting the Enterprise crew to journey to the Genesis planet to recover the corpse … where they discover that the unstable energies of the world have actually resurrected the former science officer, causing him to age rapidly from a child to an adult. The newfound “rescue mission” becomes even more dangerous with the appearance of Klingon commander Kruge (Christopher Lloyd), who’s determined to obtain the Genesis Device for himself. The Enterprise itself doesn’t survive this adventure – but, like Spock before it, this “death” will prove to be only temporary. – IFC Staff
