In pursuit of the stolen Red Dwarf, Lister and Co are attacked by Psirens - creatures who lure space-farers to their deaths with a lethal combination of telepathic manipulation and scanty clothing.
Supplies are low. The water has been recycled so often, it's beginning to taste like Dutch lager. Then a malfunctioning guidance beam drags the Dwarfers to a deserted space station...
Kryten contracts a deadly computer virus, and Rimmer and Co are forced to enter his electronic mindscape. They find themselves in a wild west town, facing a gunfight against metaphysical gunslingers.
The Dwarfers need replacement engine parts from the fearsome stomach-churningly ugly "Kinitawowi". But the GELF tribe are interested in only one trade: Lister must marry the chief's daughter.
Trapped aboard a disintegrating ship, Rimmer abandons his crewmates, taking the only remaining escape pod. As he accelerates towards a nearby wormhole, he discovers the pod has no steering controls.
When an identical ship materialises alongside Starbug, the crew are alarmed to receive an SOS call from themselves fifteen years into the future.
