As World War II looms, undercover anti-fascism organizer Kurt Muller (Paul Lukas, in an Oscar-winning turn) moves his wife, Sara (Bette Davis), and family from Europe to America, where Kurt is blackmailed by a Nazi sympathizer and driven to take drastic measures. Based on Lillian Hellman's play and adapted for the screen by her lover, author Dashiell Hammett (The Maltese Falcon), this classic spy drama earned multiple Oscar nominations.
