‘I never get the breaks,’ Rimmer (Chris Barrie) whines to Lister (Craig Charles) and his fortune doesn’t improve in this week’s energetic episode of Doug Naylor’s cult sci-fi comedy.

This week, the hapless quartet investigate a crashed ship at the bottom of an ocean moon and Rimmer discovers that a dark force controls the vessel.

Meanwhile, Lister is not only attacked by a food disposal unit but also trapped with Cat (Danny John-Jules) in the dark.

This inventive series has maintained its charm, 28 years after it was first broadcast, and the chemistry of the cast remains strong, particularly between Barrie and Charles.
