After Jessica reveals a memory about her sister and Meilhon suddenly starts talking, Touchais scrambles to fill in the gaps; as crucial pieces of Laetitia's case take shape, disturbing details come to light about someone close to the teenagers.

After a partial break in the case, the pathology report drives an irreparable wedge in public opinion of the legal system; Detective Touchais leans on Béatrice Prieur, the twins' longtime social worker, for more information about their past.

As the days continue to pass without any sign of Laetitia, Jessica grows increasingly distraught, prompting Detective Touchais to throw himself deeper into the victim's habits; Laetitia's case catches the attention of the president.

With Meilhon in temporary custody, the detectives intensify their efforts to keep him behind bars permanently, questioning those closest to Laetitia about her recent state of mind, including her devastated twin sister Jessica.
