Julien Madek, a young man of 20, is found dead at the foot of a staircase. Abducted at the age of twelve, he had just miraculously reappeared and reunited with his loved ones. Judge Nevers and Commander Marquand have the heavy task of telling the mother that her child has been taken from her for the second time. Who could Julien's return bother? In parallel with the investigation, tension rises between Alice and Marquand: he suspects her of harboring Simon, the boy who threatens his daughter.
