Professor Jérôme Hamar, 57, a specialist in organ transplants, is assassinated in the university where he was teaching. The investigation is initially oriented towards a crime of passion: he had a relationship with a young girl from the Faculty, Charlotte Thieret, but had received a text before his death for an love appointment that Charlotte did not send. Hamar's daughter suspects Charlotte, but the discovery in the Seine of the body of Philippe Rigault, a former patient of Hamar, shifts research towards the medical world.
