September is a film about the complicated choices of simple people. The internationally renowned Estonian author, Jaan Kross (1920-2007) was arrested in 1944 by the Nazis. A year after the Soviet forces entered Tallinn and he was arrested again. The accusation was the same both times: conspiracy with the underground independence revolutionaries. Based on the author's journal, pieces from his oeuvre and interviews, the film creates a story about a few monumental weeks in Tallinn, in September 1944.
