Love is the Perfect Crime

Mark, a professor of literature at the University of Lausanne, has a reputation for seducing female students. When one of them goes missing, an investigation is launched into her disappearance. Mark meets Anna, the young stepmother of the missing girl, who’s looking into the case herself.

Between his lectures and evening walks in the snowy forest, Marc finds time to embark on a passionate affair with Anna. But his situation escalates when an investigator becomes interested in the case, and Richard, the head of the literature department at the university, embarks on a relationship with Mark’s sister Marianne.
