Red Dwarf Season 7 Episode 7

Epideme

The crew come across another Jupiter Mining Corporation vessel. Everyone on it is dead except for one person who is preserved in a block of ice. They take her aboard Starbug but the ice doesn't melt, even in very warm temperatures. They decide to leave it till morning to decide what to do. During the night, the woman inside breaks out, covered in rotting skin and dead flesh and climbs into bed with Lister, who believes it's Kochanski. One thing leads to another, but when she kisses Lister, she falls dead, and Lister realises he's just taken about half her face with that kiss. It turns out it was a virus inside the woman, known as Epideme, who infects it's victims, takes their knowledge, kills them and then preserves the body and waits for another victim. Epideme has now entered Lister. After hours of trying to reason with it, they try to get rid of it by forcing it into Lister's arm and then cutting the arm off. Unfortunately, it doesn't work and Epideme begins to regenerate himself
