This is an S.O.S distress call from the mining ship Red Dwarf. The crew are dead, killed by a radiation leak. The only survivors are Dave Lister, who was in suspended-animation during the disaster, and his pregnant cat who was safely sealed in the hold. Revived 3 million years later, Lister's only companions are, a life form who evolved from his cat and Arnold Rimmer, a hologram simulation of one of the dead crew.
