Producer Bob Temple, who's brought an American show to London, loves his star Diana, but she won't take him seriously as a lover. To show her, he picks up stranger Lady Arlington, whose financier husband neglects her. On a weekend at the Arlington country house, Bob is used by both Lady A. and her friend to make their husbands jealous; this works all too well, and Bob is in danger from both husbands.
