Chief Forester Szymon from the observation tower sees a professor in the forest, walking through his district. Szymon and his wife Celina later engage in a disagreement due to his indifference and refusal to react on the professor’s illegal hunting. Celina would like to see Szymon as he used to be - rebellious, but Szymon prefers not to lean out. He is aware that everyone is responsible for the evil that permeates the country - some by their actions, others by their conformism.

The film follows the exploits of Stefan as he fights against the Nazis as a RAF pilot.
