Mark, a professor of literature at the University of Lausanne, finds his lover (one of his students) dead in her bed. Not knowing what to do, and not trusting justice, Marc hides the body.

Marc, in his 40s, is a professor of literature at the University of Lausanne. Still a bachelor — and still living with his sister Marianne in a huge, isolated chalet that they inherited when they were very young — he carries on one love affair after another with his students. Winter has almost ended when one of his most brilliant students, Barbara, suddenly disappears. Two days later, Marc meets Barbara’s mother, Anna, who wants to find out more about her vanished daughter.

Based on the book Incidences by Philippe Djian.
