Loosely based on the play of the same title by August Jakobson.
Estonia is liberated from Nazi occupation. Profesor Miylas, a noted Estonian botanist developed the unique project of swamp drainage which was later rejected. The offended researcher starts working on some purely theoretical scientific problems. He does not care about events happening in the world around him. However, his attempt to shut himself off to life fails.
Professor’s eldest son and nephew come to his house. The old scientist is horrified to find out that both worked as executioners in a Nazi death camp. The son’s attempt to kill his father makes Miylas leave his illusionary “citadel”.
The authors of the film were honored the Stalin’s Prize of the USSR.
