Aboard Starbug, Lister and the others find a promising derelict ship on the edge of a black hole. But when Rimmer warns that it could be a trap set by Gelf Vampires who feast on the blood of virgins, Cat is suddenly less enthusiastic about the salvage operation. Lister decides to board the ship, with Cat and Kryten in tow, and they disable a mercenary mechanoid and free his sole surviving prisoner, who seems to be a female Cat. Once she is brought back aboard Red Dwarf, and expresses more than a passing interest in Cat, Kryten discovers only too late that their new crewmate is not what she appears to be, and Cat could pay the price.
