 The action takes place in Moscow, Berlin and Vienna in years 1932 and 1933, a time when the great Bulgarian revolutionary and internationalist Georgi Dimitrov was actively involved in establishing a broad alliance of democratic forces against the emerging threat of war and fascism. His activities were dangerous, involving great risks. Naturally, the Nazis tried to curtail his work. He was accused of setting the Reichstag on fire and at the Reichstag Fire Trial in 1933 Dimitrov dealt an enormous moral blow to fascism. The film reveals the spirit and the atmosphere at the beginning of the thirties (the film features documentary scenes) and carries a contemporary political message.
