The story about one man- an artist and an intellectual- who was imprisoned by two brutal regimes, the Nazis and the Soviets. 'The Professor' is a man who lives by his own personal version of the Ten Commandments. After miraculously surviving imprisonment in a Nazi concentration camp through a bit of ironic fate, he writes a memoir of his life, which becomes the target of the Soviet censors. The so-called "freedom" of Communism becomes just as oppressive as the German concentration camp.

Just to add to your comments, the events on (the book) "Forest of the Gods" (which the film is based on) are based on the real experience of the main character, "the Professor" [1].
There are some criticism on whether the events are 100% faithful to the reality [2], but indifferent to that, it is a hell of a piece of art!
