Working under an alias as a doctor for displaced persons, Dr. Karl Rothe (Peter Lorre, M) bumps into his former colleague Nowak (Karl John, The Devil's General); both are keeping a low profile having worked on secret scientific research for the then-Nazi government. Nowak is curious about what happened to Rothe in the intervening years and, that night, Rothe recounts the story of how his fiancée Inge Hermann (Renate Mannhardt, The Great Temptation) sold secrets to the Allies. Inspired by a true story, Peter Lorre’s atmospheric noir - his only film as director or writer - was unpopular with audiences at the time but has since been re-evaluated as one of the finest examples of post-World War II German cinema.
