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.

After hesitating for a long time, Ariane finally accepted the marriage proposal from her partner Cédric. Dayan, who cannot help but be disturbed, invites him to explore the reasons for this sudden reversal.

Adel came back. But even though he has learned about Dayan's skills, he proves resistant to the principles of therapy. He wants to control everything, and yet the anxieties are there. Dayan tries little by little to gain his trust and find how to reassure him.

Camille is on edge. She wants Dayan to write his report as soon as possible. Dayan makes her talk about her divorced parents, and her swimming coach with whom she has a special relationship.

After the tensions of the previous session, Damien and Léonora have found a certain complicity. They have decided to take some time for themselves and stop therapy. But an unforeseen event will shake up the order of things...

Philippe has had an argument with his wife Charlotte, who has confessed to him that she has a lover. Esther takes note, and directs him to a subject that he seems to want to minimize: the ambiguity of his relationship with his patient Ariane.

Ariane arrives late because of a cat story, an excuse that Dayan doubts: is it to hide her resentment for having been rejected during the last session? On leaving their appointment, Ariane has a surprising encounter...

With an unusually cheerful air, Adel tells Dayan about his meeting with Ariane and takes the opportunity to ask him what he thinks of her. Inviting him to make the connection between his dysfunctional relationship and that of his parents, Dayan brings him back to his own torments. Troubled, the policeman tells him about a photo found at his father's house.

Camille seems worried that this third session will put an end to her meetings with Dayan. She mentions her parents' divorce and then makes important revelations about her relationship with Nicolas, her coach. Dayan still refuses to comment on whether or not his accident was premeditated, which annoys the young girl.

Dayan is grumpy, he has rather intimate medical problems. In bad faith, he accuses Esther of having given him bad advice in the management of Ariane's transfer. The latter points out to him that he was not obliged to follow her recommendations. Ariane may have awakened an old wound in him, which would go beyond the simple issue of desire and adultery.

Léonora shows up alone at the session. Dayan doesn't want to welcome her without her husband, but he still listens to her confide in her miscarriage. Damien, furious, finally arrives and violently takes Léonora to task. Shortly after, Charlotte, Dayan's wife, makes him an announcement that he doesn't like...

After a disturbing daydream, a hurt Dayan listens to Ariane tell him about her evening with Adel. The announcement of her breakup with Cédric creates a moment of complicity between them, which leads the psychoanalyst to confide part of his story to his patient. But Ariane receives a phone call that abruptly ends their peaceful exchange.

Imagining Dayan's income, Adel is outraged by the modesty of his own salary, which he considers derisory in view of the risks of his job. After a very violent training session, his anxieties reappeared during his evening with Ariane. Dayan thinks that Ariane is only a distraction for Adel, who takes him away from the real problem. He is determined to understand what the photo found at his father's house crystallizes in him.

Camille arrives at the meeting free of her casts, but exhausted from her night out the night before. At a party, she let herself be seduced by a water polo player and it left a bitter taste in her mouth. Unable to fall asleep, she remembered her accident and tells Dayan. He then discovers what she was hiding from him.

Leonora reproaches Damien for leaving their son Robin alone at home, but they find their complicity again and remember their meeting. Until Damien accuses Leonora of cheating on him. Then begins a new, violent argument, which marks a decisive turning point in their therapy.

Dayan tells Esther about his week. When he questions the ban on sexual relations between analyst and analysand, she gets violently carried away. Touched, Dayan reproaches him for not engaging emotionally with his patients, unlike him.

Ariane almost lost a 15-year-old patient, injured during the Bataclan attacks. Upset, she looks back on her own adolescence and makes important revelations about Serge, her father's friend who spent a summer with them at the time. Ariane, obsessed with Dayan and convinced that she has endangered her patient's life, sees no other solution than to stop the therapy.

Adel immediately announces that he has broken up with Ariane, convinced that she is being manipulated by Dayan. In a fit of anger, he also reveals to the analyst everything he has discovered about him: his daughter, his father in a nursing home, his wife who is cheating on him... Dayan manages to calm him down and tries to help him remember Algeria.

Angry, Camille arrives at the office with her mother, whom she is trying to get rid of. The conversation with Dayan quickly turns to her father and the supposed connection that unites them. The latter made his daughter carry a heavy secret, which she has not digested...

Leonora is alone. She accuses Dayan of having made Damien change his behavior. He has become too tender and kind for her taste, which pushes her into the arms of her lover. Dayan, by questioning Leonora about her childhood, finds explanations for his self-destructive behavior.

Dayan and his wife arrive together at Esther's. He tries to explain why he can't forgive Charlotte for his infidelity, but Esther calls him to order: he too has desire for another woman. Charlotte, jealous and exhausted by her husband's endless analyses, cuts the session short.

Philippe Dayan has a meeting with Inès, a brilliant lawyer in her forties, who is investigating a case of non-assistance to a person in danger involving the psychoanalyst. She unceremoniously prepares the latter for the ordeal of the appearance that awaits him, not without having taken care to remind him that she was briefly his patient around twenty years earlier. Dayan then discovers with astonishment the reasons which push the young woman to wish to come and consult him again…

The psychoanalyst welcomes Robin, son of Léonora and Damien (Clémence Poésy and Pio Marmaï), former patients he received as part of couples therapy. Aged eleven, the boy seems unaware of what brings him to the couch, and dreams of an "invisibility cloak". He refuses to spend time at his father's house for fear of Covid. Dayan ingeniously works to uncover the unspoken family secrets that weigh on his young patient, whose liveliness and sensitivity he discovers.

A final-year architecture student, Lydia, aged twenty-two, talks about a bad experience with a previous therapist. Dayan guides his patient to try to understand this failure. At the end of the session, Lydia reveals the real reason for her visit: devastating news about her health. She hasn't told anyone and refuses to seek treatment...

Alain, a hyperactive septuagenarian and head of a large company, has been caught up in a media storm since the suicide of one of his employees, who was a victim of overwork during the lockdown. He expects Dayan to give him “communication advice”. The therapist firmly refuses and tries to direct his patient towards in-depth analytical work.

On the advice of his lawyer, Dayan consults Claire Brunet, a renowned psychoanalyst, author of a recent highly publicized essay. Weakened and tense by the ongoing legal proceedings, he wants to question his practice. Claire immediately questions her patient's motivations, mentions an analysis rather than supervision. At the end of an intense session, Dayan comes across Rebecca, whom he has not seen for years. He is all the more troubled when he discovers that she is also in analysis with Claire.

Inès has chosen to abandon Dayan's defense in order to resume therapy with her former analyst. She has just had a fertility assessment, which shows that her chances of getting pregnant are declining. During their first exchanges, the therapist's supposed responsibility for the decision she made to have an abortion, twenty-three years earlier, emerges.

Encouraged by Dayan's caring support, Léonora and Damien finally find the words to answer their son's questions. Upset, Robin learns of their intention to divorce. Alone again with his therapist, the young boy painfully confides the mockery of his school friends, linked to his excess weight.

Since Lydia announced her illness to Antoine, her ex-boyfriend, he has been present and attentive. But the young woman refuses this help, which she experiences as an intrusion. Dayan discovers the depth of her denial and strongly encourages her to start treatment.

Overwhelmed by his professional worries, Alain is also worried about the safety of his daughter who has gone to offer her help in a migrant camp in Greece. Marked by two bereavements, the business leader is subject to frequent anxiety attacks.

Dayan's trial date is approaching. His anxiety is evident. He discusses with Claire his chance meeting with Rebecca the previous week. It's an opportunity for him to revisit his teenage loves and the trauma caused by his mother's suicide.

Inès is very disturbed by this sudden reversal of the situation. She fears more than anything the reaction of her parents. Dayan makes her measure the place she gives to family judgments, and tries to put her on the path of her own desire…

Robin had a great weekend at his father's, but the presence of his father's new girlfriend upsets him. Should he tell his mother? Dayan tries to calm the conflict of loyalty that he senses emerging in his young patient. Robin then reveals what is bothering him even more deeply in the family secrets and the relationships between his two parents.

With the architectural model she spent the night on in her arms, Lydia arrives exhausted at Dayan's. The session is tense. Lydia summons a childhood trauma by the sea, which Dayan seizes upon to make his patient observe her obsession with control. He urges her to announce her illness to her parents...

Worried because he had not heard from his daughter for several days, Alain went to Greece to join her, fleeing the media harassment he was subjected to. Surprised and angry, the young woman had a hard time dealing with her father's interventionism. Dayan tries to make his patient understand what is behind this confrontation and his repeated panic attacks.

Dayan goes to court. It is the day of the hearing in the Chibane case, which has been pursuing the analyst for five years. He answers questions from the presiding judge, then from the ruthless lawyer for the civil parties. But refuses, in the name of medical confidentiality, to discuss the content of the last session with his late patient. An unexpected witness appears at the bar…

Since she officially started living with her boyfriend, Inès feels oppressed. Dayan invites her to revisit her family history.

Leonora thanks Dayan for Robin's dazzling behavioral progress. A change too rapid not to be seriously questioned by the analyst.

Lydia still hasn't told her family about her illness. She's visibly exhausted, but she's getting ready to go to her parents' house to take care of her autistic little brother.

Lydia still hasn't told her family about her illness. She's visibly exhausted, but she's getting ready to go to her parents' house to take care of her autistic little brother.

Dayan has just learned that his father is in intensive care, suffering from Covid. He hasn't seen him for two years and clearly has no intention of visiting him.

Simon has left Inès. Upset, she makes major revelations to Dayan about the circumstances of her birth. She discovered that her mother left without her for Mali when she was only a few weeks old. She was taken care of by her grandmother during her first year of life…

Robin arrives at Dayan's two hours early. An acute situation of harassment has forced him to run away from his school. Warned by the school, unaware of the circumstances of the child's escape, his father arrives at the office furious. Dayan gets the conversation going between father and son, points out mirror effects between them and allows for calming.

Lydia is relieved. She has completed her first chemotherapy and is ready to continue treatment. An opportunity for Dayan to make his patient realize how difficult it is for her to ask anyone for help. He suggests that she get someone to accompany her during her next hospital stay.

Convinced that he has Covid, Alain consults Dayan by videoconference. Worried about him since his dismissal, his daughter is back for a while. Unable to rejoice, Alain is convinced that his daughter and his wife are plotting behind his back. He seems to be slipping into paranoia. At the end of the session, Dayan welcomes Rebecca, his former love, into his home. The latter lifts the veil on a crucial dimension of the psychoanalyst's past.

Rebecca's revelations have upset Dayan, who is still very overwhelmed by his father's disappearance. Claire invites her patient to rewrite the scenario on which he has built his vision of his childhood and adolescence based on these new elements. His father probably cared much more about him than he has imagined for decades.
