 Edgar Van Buren (Robert Colbert) holds an annual high-stakes poker game at his home, featuring booze, drugs, and women. His wife Annabelle (Tippi Hedrin) stays in her suite during the weekend to protect the dignity of her home. This year a close friend of Annabelle, Dalton Sykes (John Saxon), is invited to talk business with Edgar. But Edgar is murdered during the party, and his paramour, Laverne Carter (Cynthia Bond), is the chief suspect.
