Polish socialist and Marxist Rosa Luxemburg works tirelessly in the service of revolution in early 20th century Poland and Germany. While Luxemburg campaigns for her beliefs, she is repeatedly imprisoned as she forms the Spartacist League offering a new vision for Germany.
At the year 1946, the time of the Nuremberg Process. One of the main actors of the Second World War, who reportedly committed suicide, Adolf Hitler is, however, missing. The Czech doctor Herman (Karel Höger) is kidnapped from Prague and driven to the sanatorium of Professor Rolf Harting (Jirí Vrstála). The sanatorium is a disguised military stronghold, most probably occupied by a Nazi garrison, with prison cells and an execution chamber in the basement. At night, Herman is taken to a patient in whom he, to his horror, recognizes Hitler (Fritz Diez).
