Farscape: A Clockwork Nebari

Aeryn and Rygel return to Moya after a mind-cleansing by the Nebari. It turns out that the Nebari were after Chiana for information that would lead to her brother (who apparently had ties to the rebellion). After the crew is mind-cleansed, it's up to Crichton and Pilot to stop the Nebari from gaining control of the Universe.
