The true story of a German agent sent to the USA in 1944 in order to stop the development of the atomic bomb.

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.

This film is the first of a two-part historical and biographical portrait of the communist politician and anti-fascist Ernst Thälmann. In early November 1918, Ernst Thälmann is an unwilling soldier serving on the western front. As the revolutionary movement at home is threatened by the betrayal of the Social Democrats and fissures in the working class, Thälmann calls on his fellow soldiers to put down their weapons and unite with the workers in the communist struggle at home. Thälmann’s qualms about which side he is fighting on continue, but when the local police attempt to prevent a shipment of provisions and supplies from reaching the people in Petrograd, he intervenes and the ship is unloaded. With this moment of clarity, Thälmann continues to follow his political convictions and joins the workers at the Hamburg uprising in October 1923.
