This early postwar suspense story, based on a well-known 1926 murder trial with Dreyfus-loke overtones also represents an East German reflection on Nazism. Dr. Blum, a Jewish manufacturer living in Germany, is falsely accused of killing his booker. Even when the real killer's identity becomes evident, the state prosecutor refuses to accept Blum's innocence. The film explores German reaction to the trial and investigates the relationship between the legal system, antisemitism, and fascism, providing insight into the historical context that allowed Nazism to flourish.
