The crew of Moya stop at the ancient site of a great siege, where Peacekeeper forces once negotiated surrender to a vastly superior army. Through a freak combination of Stark's ethereal presence, and a mysterious tear in the fabric of time, Crichton and his comrades are thrust back into the past.

Materialising in the midst of the ancient siege, they accidentally change the course of events. Now as time grows short, they must discover how to set right what once went wrong - before they become history, too.

Factoid--Jool becomes a member of Moya's crew with this episode. This is signified with a scene between her and Chiana – who was Moya's most recent addition – in which Chiana recommends Jool wear better shoes.

• Wayne Pygram had to mime playing the harmonica as he didn't know what song would be used for the scene.
• A full-size courtyard was built on the lot for this episode, complete with sand and a giant statue.
• When Harvey leans back and props his cowboy boots on the table, the name "ANDY" can clearly be seen on the bottom, as an homage to Pixar's "Toy Story". Ben Browder had written it on the boots.
