被焚烧的斯蒂芬妮

A wealthy couple and their friend enter a world of sadistic fantasy games of the wealthy, but as they travel deeper, it becomes difficult to establish exactly what is a game and what is not. 　　As it begins, Paul (William Dame) is an airplane mechanic who is suddenly accosted by two older crooks in trenchcoats. They knock him out. He awakens to find himself in an older mansion, where a woman, Stephanie (Catherine Dee), seems to know him despite the fact that he's never seen her before, and an older transvestite, "Roberta" (M.R. Murphy), is keeping Paul and Stephanie captive, apparently with the intent of watching them have sex. Just who is Roberta? Is that really her motive? How did Stephanie get there? How long has she been there? Why did they pick Paul?
