A history teacher, Rainer Wenger, is forced to teach a class on autocracy, despite being an anarchist and wanting to teach the class on anarchy. When his students, the third generation after the Second World War, do not believe that a dictatorship could be established in modern Germany, he starts an experiment to demonstrate how easily the masses can be manipulated.
