Lamarck receives a call and informs Rocher of his immediate suspension until further notice. 48 hours earlier, Rocher follows a woman, sure that she is Judith Guérin though she claims to be Isabel Baron. In his first case after the surgery, Rocher attends the murder scene of Carol Wo, 51, concierge, brutally beaten in the elevator. When the PJ discovers the floor it came from, they find some mannequins representing the Gardin family, dead a year before due to lightning, and the eldest daughter, Pauline, only survivor, in shock. She has been living since the accident with her godfather Patrick Lagache, who wants her to empty the apartment to sell it. Courtène is temporarily replacing Jess, about to give birth.
