Synopsis by Hal Erickson
After a hiatus of over five months, Farscape resumed its fourth and final season with a foray into the distant past. Rescued by D'Argo (Anthony Simcoe) and the Moya crew from his wormhole odyssey, John Crichton (Ben Browder) discovers that he has inadvertently upset the Timestream. As a result, Crichton and his cohorts end up on Earth in 1986, just before John's father, Jack (Kent McCord), is about to serve as commander on the ill-fated Challenger shuttle flight. With virtually no time to spare, John tries to save his father's life, an action that will prevent the entire Farscape project from slipping into limbo. Elsewhere, the Moya crew encounter that curious native custom known as Halloween, and also attempt to steer clear of a nosy interloper.
