Roger Thornhill (Cary Grant) is not a spy. And he's certainly no murderer. Nevertheless, Thornhill's a wanted man: enemy agents want him dead, the police want him arrested, and a cool, mysterious blonde (Eva Marie Saint) just plain wants him. A victim of mistaken identity, Thornhill can't afford to make any mistakes of his own - so he embarks on a death-defying run for his life. Relentlessly pursued by plane, train and automobile, Thornhill's cross-country chase finally ends atop Mt. Rushmore where, if he doesn't watch his step, he could be in for a terrible fall.
