East Germany's contribution to the 1957 Cannes Film Festival was the wartime melodrama Betrogen bis zum Juengsten Tag. Had the film been released in the U.S., the title would probably have translated to Duped Till the Last. The film condemns the Nazi mindset by concentrating on a particularly odious cover-up. When his son is involved in the accidental killing of a girl, a Gestapo general pulls strings to save the boy from prosecution. The general manages to pin the blame for the killing on a group of Russians, whereupon he gives the men under his command carte blanche to round up and execute as many innocent Russians as they wish. This act of brutality is contrasted with the pangs of guilt suffered by the son and his co-conspirators.

In 1523, young Thomas Müntzer arrives with his wife Ottilie in the Thuringian village Allstedt to assume the rectorate. As a follower of Luther′s teachings, he finds in the Bible not only reasons for clerical, but also for secular reforms. But when Luther turns away from the rural population after a discord with Müntzer, it is Müntzer who becomes the peoples′ spokesman. He is forced to go to Southern Germany, where he convenes with revolting farmers. But his way leads him back to Thuringia. In 1525, he and Heinrich Pfeiffer form the centre of the Thuringian peasant uprising in Mühlhausen, but their success is diminished by the fact that peasants and craftsmen don′t seem to be able to work together. In Frankenhausen, Müntzer becomes the leader of a peasants′ army that is set to fighting the ruler′s army – and sustains a devastating loss. Müntzer is arrested and sentenced to death by decapitation for his insurgency.

The authorities expect the case of Friedel Walter, alias "Dr. Mueller," to be a straightforward one: he was working as a doctor without proper credentials under a false name. But Mehlin, the man in charge of his case, knows that there is more to the story. When he was injured fleeing from a concentration camp, resistance worker Irene asked her medical student boyfriend Walter to give him medical care.
