The crew play a game of
poker, with Lister attempting to teach Cat how to have a proper
poker face, but Cat failing to understand. Kryten interrupts to report on a resource-rich station to scavenge, which the crew head off towards onboard
Starbug, which requires an elaborate start-up sequence to work due to its state of disrepair. A powerful sandstorm leaves them temporarily stranded there. The crew venture through the base, encountering "cryobooths" bearing the names of
Messalina,
Vlad the Impaler,
Joseph Stalin, and
Adolf Hitler. They are then greeted by Professor Shaul Telford, who reveals that the occupants were in stasis and their arrival has triggered their release, but that they have been cured of their formerly
psychopathic ways. They are introduced to these infamous figures over dinner. Surprisingly, they prove to be kind and pleasant, and claim to be completely reformed. Lister gets to know Hitler, and the pair perform "
The Happy Wanderer" on guitar. The rest of the crew pull Lister aside to chastise him for socializing with Hitler, but are all knocked unconscious and put into separate torturous scenarios. After escaping from their traps, the crew meet up and accuse the base occupants of trying to kill them. They decide to test everybody using a device that scans who among them is a psychopath, which returns the results that of them two are psychopaths, one being the Cat, due to his inherently selfish and vain personality, and the other being Professor Telford. Telford reveals himself as the base's real patient, with the other occupants having been his android caretakers, who he reprogrammed. Telford holds the crew at gunpoint, but due to not knowing how to start
Starbug, offers to take the Cat with him. Cat, seemingly, agrees and requests a gun to kill the other three with, only to immediately kill Telford with it. He credits his deception to his newly-learned poker face. ==Production==
