Frozen Dinner (S03E11)

The Sealab team embarks on an audacious rescue operation at Ice Station Zebra, where one of the residents has resorted to cannibalism. They are joined by a German man who "came with the sub," strikingly similar to Jürgen Prochnow, and has a penchant for firing his gun inside the submarine while exclaiming, "Sieg Heil, Cornelius Drebbel!" Regrettably, the mission to save the two residents of Ice Station Zebra fails, as they lack wetsuits—thanks to Debbie bringing along a stylish dress for herself instead.
