When a Starburst goes badly wrong, Moya collides with a Nebari ship. On board is Durka, Rygel's former torturer, who has been mind cleansed and now serves the Nebari. Chiana, an attractive young rebel faces the same fate. Rygel takes it upon himself to take revenge on Durka and ends up undoing the cleansing and restoring him to his former, tyrannic incarnation.

A Peacekeeper ship approaches Moya, so Crichton and Aeryn pose as Peacekeeper officers on a secret mission while everyone else gets locked into cells to make the deception seem realistic. The Peacekeepers that come aboard, however have some strange and dangerous cargo aboard which wreaks havoc when accidentally released by Rygel and Chiana snooping through the Peacekeepers' possessions.
