Rimmer is suffering from stress and Kryten prescribes several measures for him to prevent an electronic aneurysm. Meanwhile, the crew decides to replenish supplies by looting the Simulant ship they shot down a few weeks ago ("Gunmen of the Apocalypse"). One of the Simulants has survived and confronts Lister, Kryten and the Cat. Rimmer, however, sneaks into an escape pod and runs away which causes the destruction of the ship. His pod subsequently heads straight for the closest S3 planet, on the other side of a wormhole, and when it arrives Rimmer decides to use the terraforming equipment to create a paradise. He also manages to clone himself, hoping for female company, but instead begins an entire new race of Rimmer-clones who eventually turn against him and imprison him in a dungeon. When his shipmates arrive in Starbug a time dilation effect means that for Rimmer 600 years have passed. They arrive on Rimmerworld only to be promptly captured and thrown into Rimmer's dungeon by power-hungry Rimmer-clones, who consider anything un-Rimmer like to be a crime (i.e., charm, bravery, intelligence). The crew teleport out of the cell and escape with Starbug.
