Consenting Adults (1992)

Richard and Priscilla Parker(Kevin Kline & Mary Elizabeth Mastrantonio) are living a happy normal life. Then they get some new next door neighbors Eddy and Kay Otis.(Kevin Spacey & Rebecca Miller) The new neighbors are friendly outgoing and love to live life to the fullest, even if it means breaking a convention or two. Things go along well for the two couples until the night Eddy proposes something a little too out of the ordinary for the Parkers. And what the Parkers don't know is that Eddy's games are just a prelude for something more sinister that is intended to destroy their lives.
