Leo suspects Sonja of infidelity, although she is in fact – for better or worse – fraternising with militant nihilists. One evening, Leo secretly follows her and ends up in the clutches of the nihilists, who give him an ultimatum that puts his life at stake. If Leo can obtain the police’s list of their cronies facing execution within three days, he and Sonja will be allowed to live. (Stumfilm.dk)
