The action takes place in a central German town in the 1920s. A Jewish factory owner is accused of murdering his accountant. The German nationalist investigating judge, who is determined to have a Jewish perpetrator, still sees Blum as the perpetrator even when evidence of the actual murderer, a former Freikorp fighter, is found. The Social Democratic court president from Berlin sends a criminal investigator to tear apart the judge's chain of evidence.
