Cary Grant gets Ingrid Bergman to spy for the US on Nazis in Brazil, but a relationship develops between them. She is spying on Claude Rains who also falls in love with her. Ingrid Bergman gives one of her great performances and Alfred Hitchcock produces some innovative work as well. There is also good support from Calaude Rains as he unusually in Hollywood films portrays a Nazi with a heart.
