In the second episode of a three-part story, John Crichton (Ben Browder) has managed to rescue Aeryn (Claudia Black) and is heading for Katratzi, the secret and hitherto elusive Scarran base. A message from "beyond" informs John that the duplicitous Scorpius (Wayne Pygram) is in full possession of the precious wormhole secrets. Now John must rescue Scorpius from his Scarran torturers -- or die in the process, the inevitable result of the nuclear bomb rigged to explode if John should meet with harm. ~ Hal Erickson, Rovi
