A psychoanalysis office in the 11th arrondissement of Paris. Ariane, a young surgeon, has been Philippe Dayan's patient for a year. After the attacks, she found herself on the front line at the hospital and spent a nightmarish weekend. However, today, she is not just here for that: she finally feels ready to share a dark secret with her therapist...

Dayan receives a new patient: Adel Chibane, police officer at the BRI. Adel was in the intervention team that entered the Bataclan on the evening of November 13. Since then, he has had symptoms of stress that he cannot explain. He makes contact with Dayan, full of reservations and mistrust.

Camille, 16, is a young high-level swimmer who is training for the Olympic Games. She comes to Dayan's office following a bicycle accident, both arms in plaster. Her insurance requires a psychological assessment attesting that she is in no way responsible for what happened to her.

Dayan is not an expert in couples therapy, but he agreed to see Damien and Léonora, who have lived together for ten years. Recently, Léonora became pregnant even though the couple had given up on having a second child. The crisis they are going through seems insurmountable. They expect Dayan to help them make a decision about this unborn child... or to make it for them.

Dayan rings the doorbell of Esther's office, a former friend and widow of his mentor. She was also his analyst and his controller, but Dayan has not seen her since the day when, in the middle of a session, he slammed the door. But today he is ready to forget old quarrels, desperate to find a new balance in his practice.
