What is the plot?
La saison 5 s'ouvre sur une enquête autour du meurtre d'Alice Allio, une bibliothécaire sans histoire, dont la mort entraîne Astrid et Raphaëlle dans une affaire qui les met très vite face à des indices troublants et à des pistes qui s'entrecroisent.
Au fil de l'enquête, les deux femmes se rendent compte qu'elles ne suivent pas une simple affaire isolée. Elles croisent la route d'une sans-abri, présentée d'abord comme une témoin marginale, mais qui apparaît ensuite comme potentiellement plus liée au dossier qu'il n'y paraît.
Sur ordre de ses supérieurs, le commissaire fait intervenir une profileuse. Cette nouvelle enquêtrice rencontre Astrid, qui l'admire immédiatement, et Astrid se retrouve alors à travailler temporairement sans Raphaëlle, dans un duo inédit centré sur la documentation criminelle de Paris et l'étude d'anciennes affaires pour relier les différentes victimes possibles.
Dans un autre volet de la saison, une enquête menée sur le tournage d'un plateau de cinéma commence comme un accident apparent après la mort par balle d'un acteur, mais l'affaire bascule rapidement vers un meurtre préparé avec soin. Les téléspectateurs apprennent dès le début du dernier épisode que le véritable cerveau derrière cette intrigue n'est autre qu'Alain Lamarck, l'ancien ennemi d'Astrid, revenu après sa disparition de la saison 3.
Astrid relie alors l'affaire à ses propres crises et à ses visions. Elle en vient à se convaincre qu'elle a elle-même tué Denis Chartreux autrefois, d'un coup de fourche, et cette conviction la renvoie directement à ses traumatismes et à sa culpabilité ancienne.
La vérité s'éclaircit ensuite grâce à la détermination de Raphaëlle. Les deux femmes finissent par remonter jusqu'à Alain Lamarck, qui a orchestré l'ensemble des événements, et Raphaëlle le tue dans un premier dénouement sanglant, ce qui fait tomber le masque de la manipulation et permet à la vérité d'émerger.
Après la mort de Lamarck, un élément essentiel du passé est révélé: ce n'est pas Astrid qui avait tué Denis Chartreux. C'est finalement Samy, l'ami d'Astrid, qui avait saisi la fourche des mains de la jeune fille et avait porté le coup mortel par accident.
Mais Lamarck a encore préparé un dernier piège. Dans le final, alors qu'Astrid et Tetsuo célèbrent leur mariage, Samy devient une victime collatérale de la vengeance de Lamarck, qui le prend en otage et le menace avec une arme.
Alors qu'Astrid est sur le point d'épouser Tetsuo, Raphaëlle remarque l'alliance de son amie et décide de l'enfiler. La bague a été piégée: une pointe ou une aiguille imprégnée de poison la blesse, et elle s'effondre presque aussitôt, comprenant que Lamarck a orchestré cette dernière vengeance avant de disparaître.
La fin de saison se clôt sur cette image brutale de Raphaëlle au sol, empoisonnée au moment même où le mariage d'Astrid bascule dans le chaos, laissant planer l'ombre du dernier coup de Lamarck sur les héroïnes.
What is the ending?
Astrid and Raphaëlle's season 5 ends with a deadly trap laid by Alain Lamarck at Astrid's wedding, and Raphaëlle is poisoned when she tries on the ring. Lamarck is killed before he can finish his plan, and the final image leaves Raphaëlle collapsing as Astrid's marriage ceremony is suddenly turned into a medical emergency.
Astrid and Raphaëlle are on the final stretch of the season when the last investigation brings them back to the truth behind Lamarck's return. He has resurfaced after disappearing in season 3, and this time he is using a carefully prepared scheme against Astrid.
The ending unfolds first in the confrontation with Lamarck. Astrid tracks him down after the investigation leads her to his hiding place, where he is holding one of her friends hostage. He threatens them, keeps control for as long as he can, and leaves behind one last cryptic message before the situation turns fatal for him. Raphaëlle intervenes and shoots him, and Lamarck dies there, ending the immediate threat from him.
After that, the story shifts to the wedding of Astrid and Tetsuo. The celebration is supposed to be a moment of peace after everything that has happened. Astrid is at the altar, still carrying the weight of Lamarck's final words and still unsettled by his last warning. Raphaëlle, standing nearby, takes the ring and slips it on to try it out.
At that instant, the trap is triggered. A hidden poisoned needle inside the ring pricks Raphaëlle, and she suddenly collapses. She realizes in the moment that the poison was planted by Lamarck before his death, meaning his final act was designed to strike even after he was gone. The ending stops on that shock, with the wedding interrupted and Raphaëlle in immediate danger.
Astrid's fate at the end of the story is that she survives the confrontation with Lamarck and reaches her wedding ceremony, but the day is thrown into chaos by Raphaëlle's collapse. Raphaëlle's fate is left in danger at the end of the episode, though the reporting indicates she is expected to survive. Lamarck's fate is death, killed after the final confrontation. Tetsuo's fate at the end is that he is present at the wedding and witnesses the crisis as it breaks out around Astrid. Samy's role in the ending is that he is part of the hostage sequence during Lamarck's last stand, and the earlier mystery is resolved when it is revealed that he had accidentally killed Denis Chartreux years before after taking the pitchfork from Astrid.
Is there a post-credit scene?
There is no evidence in the available episode descriptions or coverage that the Season 5 finale of Astrid et Raphaëlle includes a post-credit scene.
What is documented instead is that the last episode ends on a cliffhanger: during Astrid and Tetsuo's wedding, Raphaëlle tries on Astrid's ring, is pricked by a hidden poisoned spike planted by Lamarck, and collapses after realizing she has been poisoned. Coverage and the episode listing describe this as the final beat of the season, with no mention of any extra scene after the credits.
If you want, I can also describe the final scene itself in detail, shot by shot, based on the available coverage.
What is the role of Alain Lamarck in season 5, and how does he connect to Astrid’s past?
Alain Lamarck returns as the season's central hidden antagonist after having disappeared from the series earlier, and the final episodes reveal that he is manipulating events behind the murder investigation and targeting Astrid personally. The season ties him to Astrid's trauma by making her believe he knows details about her marriage and by using that knowledge to destabilize her before the wedding.
How does Raphaëlle get poisoned in the season 5 finale, and is she in danger of dying?
At Astrid's wedding to Tetsuo, Raphaëlle slips on Astrid's ring and is pricked by a poisoned needle hidden in the jewelry, then collapses in front of the wedding guests. The reports describe her as being in a life-or-death state at the end of the season, while one source says the character is expected to survive and continue into the next episodes.
Who is responsible for the murder linked to the final investigation in season 5?
The final investigation initially looks like a straightforward on-set killing, but it is revealed that Alain Lamarck is orchestrating the crime from behind the scenes. The story also clarifies an older mystery involving Denis Chartreux: Samy, Astrid's friend, had actually taken the fourche from the young Astrid and accidentally killed Denis years earlier.
What happens to Astrid and Tetsuo’s wedding in season 5?
Astrid and Tetsuo do get married at the mairie, but the ceremony is overshadowed by the fallout from Lamarck's final scheme and Raphaëlle's collapse. The wedding becomes the setting for the season's sharpest twist, with the poisoned ring turning a personal milestone into an emergency.
How is Samy involved in the season 5 finale?
Samy becomes a key victim in Lamarck's endgame, as Lamarck takes him hostage and threatens to kill him. Beyond that immediate danger, the finale also reveals Samy's hidden role in Astrid's childhood trauma: he had taken the fourche from Astrid and accidentally killed Denis Chartreux years earlier, which changes Astrid's understanding of that long-buried event.
Is this family friendly?
Yes--mostly family friendly for older children/teens, but it is not ideal for very young kids because Astrid et Raphaëlle is a police/crime series with murder investigations, tense scenes, and some emotional heaviness.
Potentially upsetting or objectionable elements in season 5 include:
- Murders and violent crime investigations, including episodes centered on a killed actor, a hitman, and other dangerous criminal cases.
- Poisoning / attempted poisoning, including a finale scene where a character collapses after contact with a poisoned ring.
- Threats to main characters and a cliffhanger-style ending that can feel intense or alarming.
- Emotional stress and anxiety, since the season includes major personal upheavals and "rebondissements" in the characters' lives.
- Criminal and secret-service intrigue, which may be confusing or unsettling for younger viewers.
- Themes of death, danger, and deception, common to the show's detective format.
If you want, I can also give you a simple age recommendation like "okay for 10+ / 12+ / 14+" based on this season's content.
