Red Dwarf has been stolen, and our intrepid heroes are hot on its trail. Starbug, unable to match its speed, has to take a shortcut to overtake it. Unfortunately this involves going through a very dangerous area which is patrolled by rogue droids that absolutely despise humans. Rimmer creates a world populated by his clones, Lister gets married, Kryten becomes Sheriff in the Wild West, and they all meet their future selves who want to kill them.
