Rhonda, Paul and Muriel form a love triangle with a difference - they are drawn together by their love of bondage. There lives are spent in and out of one another's beds, changing roles as the mood strikes. Rhonda is the true dominant and Paul is attracted to her as his mistress. Yet he is also drawn to Muriel, the submissive bank manager, who loves to be restrained and ravaged. They plan a trip to Rhonda's country house, where they fulfill their mutual desires for domination, submission, pain and pleasure.
