Receiving a tip from his dentist Jack Shorter, Inspector Peter Pascoe takes a closer look at the Calliope Kinema Club, a film club notorious for showing adult entertainment movies. Shorter is convinced that one particular scene in a movie he recently saw was too realistic to have been staged with fake blood, but when Pascoe starts investigating, he soon comes across the actress in question, Linda Abbott, who obviously didn't suffer from any harm and assures Pascoe that his and Shorter's concerns are unnecessary.
