The main setting of the series is the eponymous mining spaceship Red Dwarf. In the first episode, set sometime in the late 22nd century, an on-board radiation leak kills everyone except lowest-ranking technician Dave Lister, who is in suspended animation at the time, and his pregnant cat, Frankenstein, who is safe in the cargo hold. Following the accident, the ship’s computer Holly keeps Lister in stasis until the radiation levels return to normal – a process that takes three million years. Lister therefore emerges as the last human being in the universe – but not alone on-board the ship. His former bunkmate and immediate superior Arnold Judas Rimmer (a character plagued by failure) is resurrected by Holly as a hologram to keep Lister sane. They are joined by a creature known only as Cat, the last member of a race of humanoid felines that evolved in the ship’s hold from Lister’s pregnant cat during the 3 million years that Lister was in stasis.
