Synopsis by Hal Erickson
Arrested on a trumped-up charge, Don (Mark Goddard) and Dr. Smith (Jonathan Harris) are sentenced to hard labor on a brutal intergalactic prison colony. A fellow convict named Creech (future Hill Street Blues costar Michael Conrad) approaches the pair with a desperate escape plan involving a booby-trapped cake. Smith likes the plan, Don hates it, and the Robot dons a chef's hat to do the baking! Several of the costumes and much of the facial makeup in this episode was "borrowed" from the recently completed Planet of the Apes.
