Delphine Perrot, family doctor, makes a phone call in the street at 6 a.m. and leaves a message to her son Jérémy, apologizing. Near her car, she gets a gunshot in the femoral artery and bleeds to death. The boy had just undergone a kidney transplant, though he was on the transplant waiting list, which could mean a case of organ trafficking. Everything points, however, to his biological father, who had just learned of Jérémy's existence. Meanwhile, Alice and Marquand face the return of Chahine and Léa.
