Cynthia has been having an affair with her sister’s husband, John. When John’s old friend Graham shows up in town, not only is John’s wife Ann drawn to him, but so is Cynthia. She even goes to his house and makes an “interview” tape on which she masturbates. Ann is appalled, and so is John, for a different reason. He shows up at Cynthia’s to fool around, full of judgment.
