Notorious

At the end of World War II, American military intelligence recruits the daughter (Bergman) of a convicted Nazi to infiltrate a group of Germans hiding in Brazil. Paired with a cool agent (Cary Grant), she falls deeply in love with him, but his distrust due to her past shatters their bond when she marries the group's leader (Claude Rains) for insider access. This union sparks a web of deceit and betrayal, trapping her in an enemy's home where discovery of her mission means certain death.
