Summary: Bruce's fiancee, Julie, has become an actress. She has a part in a horror film, a remake of an old Basil Karlo picture. The lead actress is murdered, and the suspicion is on her two men: her ex-boyfriend and the former director of the film who had been fired. Later it is revealed that the murders were committed by someone called 'Clayface', who turns out to be Basil Karlo, who didn't want his film remade with a new star.
