Joyce Benderman (Markie Post) thought she had made the dream marriage. Her husband, Stan (Corbin Bernsen), is a successful, handsome dentist, and Joyce, who grew up in poverty, cannot believe her good fortune. But her charismatic husband has a dark side that is about to engulf and destroy Joyce's entire world. In rapid succession she discovers that he is a philanderer who enjoys sexually ensnaring and manipulating young women; and, more appallingly, he may be the ruthless killer behind a series of atrocious murders. Scared to death of the man she used to love, and reeling from the unspeakable horror of her newfound knowledge, Joyce agrees to aid a federal agent (Kelsey Grammer) with an elaborate plan to entrap Stan into admitting his guilt. To force his confession and avoid his suspicion, Joyce must play her husband's games. And she must win.
