Based on a true story, this film is set during the German occupation of France during World War II and centers on a British countess named Mary Lindell. Working for the Red Cross, Lindell secretly smuggles Allied airmen stuck behind enemy lines out of the country. Lindell helps downed fighter pilot Maj. James Leggatt, but once he is smuggled out, Lindell herself is arrested and sent to prison, and eventually to a concentration camp.
