Crichton and Chiana try to infiltrate a Peacekeeper base to get a vital tissue graft for Aeryn, who will die without it. Crichton gets caught by Scorpius and imprisoned. He is tortured using a device called the 'Aurora Chair' which is able to look inside his mind and, as Scorpius wants, to reveal the secrets of wormholes.

Moya is hiding in an asteroid field from a Peacekeeper command carrier. They receive a distress call and Crichton, Zhaan and D'Argo go down to one of the asteroids to rescue a woman who becomes intent on eating them.
