Seven Days in May

Military aide Martin Casey (Kirk Douglas) stumbles across a plot by his boss (Burt Lancaster) to overthrow the U.S. president (Fredric March), who has just negotiated a controversial peace treaty. Casey's dilemma: Follow orders and remain silent, or betray his boss. Director John Frankenheimer demonstrates the same mastery that made The Manchurian Candidate a classic, and Lancaster gives an effective performance in an unsympathetic role.
