Lister loses Rimmer in a game of poker to a group of Biologically Engineered Life Forms and in return gets an unwanted gift: a groinal exploder programmed to detonate in 24 hours unless Lister pays his debts. Meanwhile Kryten and Cat become quantum entangled and do everything in perfect unison.

Hiding in an Asteroid, surrounded by a Simulant Death Ship and a fleet of Annihilators, the Dwarfers begin to wonder whether this is the beginning of the end. Only one man can save them. Unfortunately, that man is Arnold J Rimmer.
