Among a cliquish set of country club doctors and surgeons, it seems that sleeping around is the norm. Early in the film, however, one husband murders his promiscuous wife (Dyan Cannon) while she is in bed with a rather unlikely adulterer. The various alliances and rivalries in this close-knit community are further stressed as the murderous husband uses his knowledge of the community for a wide-ranging blackmail scheme. While the police investigate, the doctors who do open-heart surgery on their patients experience heart-rending situations themselves. The film has a large and distinguished cast of actors, including Richard Crenna, Dyan Cannon, Caroll O'Conner, Ralph Bellamy, Gene Hackman, John Colicos, Diana Sands and Janice Rule. The story is based on by Frank G. Slaughter.
