Cary Grant stars as an innocent man mistaken for a spy in one of director Alfred Hitchcock's greatest thrillers. While leaving New York's Plaza Hotel, advertising executive Roger Thornhill (Grant) has the misfortune of standing just as the name " George Kaplan" is paged starting a lethal case of mistaken identity & a nonstop game of cat & mouse as he is pursued across North America by espionage agents trying to kill him & by police who suspect him of murder.
