University student Kuno Totono is the type who constantly questions what is taken for granted in society and develops his own theories based on his vast knowledge and unique set of values. One day in autumn, the police come to see him. His university schoolmate has been murdered at a park nearby and the police apparently regard Totono with suspicion. He is asked to come with them for questioning. In the interrogation room, the police are manipulated by Totono who tends to digress from the topic and poke at their contradictions. He even correctly guesses that one of them is troubled about not getting along with the wife and ends up giving advice. However, Totono’s fingerprints are eventually discovered on the murder weapon.
