Professor Hans Mamlock is the distinguished chief of surgery in a university hospital. The year is 1933, and although the Professor is Jewish, he remains unconcerned with politics and the growing Nazi threat. Mamlock identifies strongly as a German, and he believes his culture to be simply incapable of the common barbarism associated with the Nazi party. Accordingly, he shows little understanding for people with strong or unpopular political views, such as Walter, a patient, and Rolf, his own son. Indeed, when Rolf joins the communists in resisting the Nazis, Mamlock throws him out of his house. As the persecution of Jews intensifies during the 1930s, Mamlock's own daughter is targeted for anti-Semitic attacks at her school...
Albert Hauptmann is an out of work waiter in Cologne who is often confused with a former Captain of the Nazi Army. Albert uses this to his advantage and becomes the Director of the Montan Corporation, and a member of the West German Parliament. Herr Karjanke, the real Captain, learns of Albert’s ruse, and wants to claim his "rightful" position in Parliament. But Karjanke cannot come forward until his politicking "Doppelganger" succeeds in passing an amnesty law for war criminals. When Albert is finally brought before a judge on charges of fraud, he learns that this own amnesty law does not apply to him.
