An city modern movie about adultery, homicide and betrayal within the movie noir fashion. A easy story to which the director imparts a sense of unrest and disquiet, catching town in its numerous moods. The movie breaks generic conventions, notably within the presentation of the personal detective by means of his deglamourised life and his technique of discovery of 'who did it'. It isn't constructed by means of his viewpoint in any respect. In reality the policeman and the detective, the very fact finders, are at the hours of darkness concerning the crime, to the very finish.
