She runs off to a train where she meets Jana - a quiet and shy woman in her late 30s. Jana travels to her cottage, deep in the mountains. That’s a chance for Marika to take a refuge. The days go by in quiet melancholy, and the suspicion between the two women as to their true intentions gets stronger. “Three Days in September” is a chamber, character driven thriller that deals with the consequences of sexual abuse in our society. It is most of all a character study where the two women retrieve, through their mutual relationship, step by step, their secrets and traumas.
