Montpellier University. A teacher, Nathalie Josserand, 45, is found dead in the lecture hall. First suspect for Elli: David Crosnier, 35, a teacher in whose home the murder weapon is found. Nathalie’s former partner, he is involved in a romantic relationship with one of his students… who is none other than Maryam, Elli’s sister! The relationship between Elli and Maryam (who defends David despite the evidence against him) is put to the test, especially since Elli informs her sisters that she will be forced to sell their family home… While Elli focuses on David, Clément hones in on another suspect, Stéphane Rocques, president of the university. He seems to have a secret that he wants to preserve at all costs…
