The notorious propaganda film set in the period immediately before the Nazis′ rise to power. The Brand and Baum families live in a Munich tenement. Father Brand, a Social Democrat, scorns his son (Fritz) for joining the SA. Anni Bauman is, like her parents, a member of the Communist Party. Nevertheless, she is attracted to Fritz Brand, and when she is given an assignment to trap him, she lets him in on the party′s schemes. As the SA is raiding a Communist cache, Fritz is wounded in crossfire. On his hospital bed, father and son come back together, and Anni opens up to Fritz. Following his discharge, the NSDAP marches through the residential quarter, and in the midst of it the young SA-Mann Lohner is shot by a Communist. The film ends with the electoral victory of the National Socialists and the arrest of their political opponents.
