October 1918: Karl Liebknecht is released from prison and Berlin workers celebrate his release. Although WWI is almost over, the German Kaiserreich in vain sends its last reserves to the slaughter. The working class is in a rebellious mood; the uprising of Kiel’s sailors against war and militarism sets off a call for revolution led by Liebknecht. On November 9, Liebknecht declares the Free Socialist Republic of Germany. But pro-Kaiser military and right wing Social Democrats oppose him.

The communist and resistance fighter Lorenz Reger, who after the war put all his efforts in the creation of a socialist German state, learns that he has only a short time left to live. Nevertheless, he wants to take on one last difficult new task: He wants to restructure a large firm which has run deep into the red numbers. In a short amount of time, Reger manages to establish mutual trust between the employees and the new management. Furthermore, he motivates the employees with his personal interest for their concerns.

Gregor is a young soldier entering Germany with the victorious Soviet troops at the end of WWII. But he is also the child of left-wing Germans who fled from Hitler and spent the war in the Soviet Union. As a result, his return to Germany is ambivalent; he finds he is a stranger in his own land. As they enter Germany, Gregor begins to realize that he is different from all his comrades in arms, for this defeated land is his home country, the Germans he meets are his compatriots. He is a victor, but also one of the vanquished. He attempts to understand the Germans he meets along his way, but he is a 19-year-old: inquisitive, occasionally uncomprehending and repeatedly dismayed by the atrocities and lies he encounters.

This is part one of a two-part biopic about Karl Liebknecht. In 1914, Germany is arming itself for war. Karl Liebknecht, left-wing revolutionary Social Democrat, workers’ leader and a virulent antimilitarist, is one among 110 SPD members of Parliament who vote against approving war loans. From then on, he is considered un-German and a traitor to the fatherland, and his own party’s leadership turns against him. Despite threats, Liebknecht speaks up against the war and writes the manifesto “The Main Enemy Is at Home.” Even when he is arrested and charged with treason, he does not surrender.

After a breakdown, Rita returns to her childhood village in 1961. As she recovers, she remembers the past two years: her love for the chemist Manfred, ten years her senior; how his enthusiasm about his new chemical process turned to bitter disappointment in the face of official rejection; how he escaped to West Berlin a few weeks before the Wall was built and hoped that she would follow him …
