Jack and Kay attend a swingers' party at a country hotel, but the night quickly descends into disaster when Jack finds an inconsolable Doug, who claims that he has accidentally killed his latest sexual partner when a game of foreplay went too far. Doug persuades Jack to help him dispose of the body, but after a close shave with the police, Jack is led to believe Doug may have lied to him all along when the woman he is supposed to have killed turns up in the hotel bar where Jack is holding a business meeting.
