Having just arrested the flight attendant for the murder of the plane's passenger, the team is sorry that they can't catch their rapist, Ransom, who is responsible for the original trauma. Investigators come up with a plan to catch him. Kelly will have to pretend to have been assaulted by Jackson in front of Ransom. Jackson hopes to become acquainted with Ransom, gain his trust, and obtain his confession. At the same time, Clarissa, still in conflict with her daughter Agathe, is more disturbed by the investigation than she is willing to admit. She confides in Joséphine about her traumatic past in a brigade in France.
