While visiting a Peacekeeper memorial, Stark accidentally sends himself, Crichton, D'Argo, Aeryn and Jool back in time where they alter the timeline and then are forced to interfere further to restore it.

Moya and Talyn, who is seriously damaged, rendezvous. They hide in the atmosphere of a planet to prevent the Peacekeepers from finding them. D'Argo and Rygel go down to the planet to find some Chromextin, a drug that will help Talyn recover. Meanwhile, Aeryn learns more about her parents and there are two Crichtons on board continuing from the last episode.
