While vacationing in Morocco, American tourist Ben McKenna (James Stewart) learns of an assassination plot but can't turn to the police without endangering his young son, who's been kidnapped to ensure McKenna's silence. Director Alfred Hitchcock's suspenseful remake of his 1934 thriller features a rare dramatic turn by Doris Day as Ben's wife and makes legendary use of the Oscar-winning tune "Whatever Will Be, Will Be (Que Sera, Sera)."
