Hitchcock's classic thriller stars Joel McCrea as Johnny Jones, a naïve New York reporter sent on assignment to Europe on the eve of World War II. Amidst the volatile atmosphere of the impending war, Jones stumbles on a deadly conspiracy devised by Stephen Fisher (Herbert Marshall), whose spy ring masquerades as a peace organization. Fisher's daughter Carol (Laraine Day) lends a hand as Jones races to expose the story -- and tries to stay alive.
