In a remote Slovak village in the closing days of World War II, a schoolteacher and his young wife find a wounded Russian parachutist in their front yard just as the Germans are coming in to occupy their village. As his wife readily becomes involved with anti-Nazi partisans, the schoolteacher collaborates with the Germans in fear.

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).
