Professor Sonnenbruck is a scientist who is not particularly interested in politics. Even the meeting in 1943 with his former assistant Peters does not change him. He does not betray Peters, who has escaped from a concentration camp, but that is already enough for him. But after the war Sonnenrbruck gets into a conflict of conscience. He thought that science was finally free of politics again only to find the opposite happening at his university in Göttingen. A medical congress in the GDR brings him together with Peters, who is working on a major research contract there. Sonnenbruck decides to visit Peters.
