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.
Country Dr. Robert Koch is desperate: a tuberculosis epidemic is decimating the children in his district and no one is able to do anything about it. Every fourth child is already sick and the parents must helplessly watch as their young ones die. Now Koch is undertaking to find the cause of the tuberculosis --- something he has already been working on for years --- which has been causing this plague of illness. His work is made more difficult by envy; for example, that of his teacher, who was wounded defending his honor. But his greatest obstacle is the famous Berliner scientist and Reichstag deputy, Privy Councilor Rudolf Virchow: He is extraordinarily skeptical of Koch's theory, that the cause for tuberculosis is a bacteria.
