Twelve years have faded from the memory of police captain Gabrielle Moscato, played by Odile Vuillemin, when the disappearance of her daughter resurfaces in a small town in the Grand Est. Broadcast in January 2026 on France 2 and RTS 1, the mini-series Il était deux fois) explores, between investigation and dark tale, the vertigo of grief, guilt, and broken memory.
A French mini-series presented as an event
A six-episode mini-series of 52 minutes each, Il était deux fois is part of the new wave of psychological thrillers produced in France. A co-production of Marathon Studio and Terence Films (Banijay France Group) for France 2, the series was first released in its entirety on france.tv on December 26, 2025. Even before its broadcast, it accumulated nearly 5 million views on the service. Thus, it becomes the best historical start of a fiction.
In Switzerland, the broadcast begins on January 6, 2026, on RTS 1. In France, France 2 then schedules the series from January 7 to 21, 2026, on Wednesdays at 9:10 PM, in batches of two episodes. A hybrid setup — platform first, prime time later — illustrates a new trend. Indeed, major public channels are now adjusting their fictions to the habits of streaming.
A free adaptation of the eponymous novel by Franck Thilliez, published in 2020 by Fleuve éditions and sold over 500,000 copies, the mini-series is created by Éric Delafosse and France Jacquet, and directed by Florian Thomas and Valentin Vincent. It was presented in preview at the La Rochelle Fiction Festival 2025. This took place in the "Suspense" category of 52-minute series.
An investigation in dual timelines: 2013 / 2025
At the center of Il était deux fois, there is a disappearance and a black hole in memory. In 2013, police captain Gabrielle Moscato (played by Odile Vuillemin) investigates the disappearance of her daughter, Julie, in a small town in eastern France. Exhausted, the policewoman falls asleep in a hotel room. When she wakes up, it is 2025.
Twelve years have evaporated from her memory. Gabrielle suffers from atypical psychogenic amnesia. She has forgotten everything that happened between these two dates. However, she has lost neither her cop instinct nor her motherly instinct. Around her, relationships have been reshaped, colleagues have changed, and so has society. One thing, however, remains: her daughter has never been found, and the investigation is officially closed.
The series then organizes its narrative in dual timelines 2013 / 2025. Scenes from the past investigation blend with investigations relaunched in the present. This happens as memories resurface and clues reappear. Without revealing the many twists, Il était deux fois constantly plays on the boundary between reality, nightmare, and mental reconstruction, leaving doubt about what Gabrielle has truly experienced.
From Franck Thilliez’s bestseller to a television heroine
The novel Il était deux fois already established itself as a dense mental thriller. It is imagined around a gendarme confronted with the disappearance of his daughter and a notebook found in a hotel. Published in 2020, it is among the great successes of Franck Thilliez, a Lille-based author who has become one of the references in crime and thriller in France, with about twenty novels to his name.
For the adaptation, Éric Delafosse and France Jacquet made a major shift: the male hero of the novel, Gabriel, becomes Gabrielle, a police captain. This change of perspective is at the heart of the project. It refocuses the narrative on the experience of a mother facing loss and guilt. Consequently, the obsession continues to guide her actions twelve years after the events. The screenwriters explain that they saw it as a way to more directly address maternal grief. This allows the series to stand out from the many very faithful adaptations. Indeed, these merely transpose a character to the screen.
This mini-series also extends a broader trend: Franck Thilliez’s universes are increasingly permeating French television. After Syndrome E for TF1 and Vortex for France Télévisions, Il était deux fois adds to the list of projects where the author is involved as a source or as a screenwriter, a sign of the anchoring of genre literature in the schedules of major channels.
Odile Vuillemin, a heroine in constant tension
To portray Gabrielle Moscato, the production chose Odile Vuillemin, whom the public knows notably for her roles in the series Profilage or several TV films centered on social issues. Here, she plays a woman deprived of twelve years of her own life. Thus, she progresses in a minefield in her profession. Moreover, she advances cautiously in her intimacy as well.
The actress creates a character that is both physical and restrained. The body is often tense, the gaze fixed on details, the voice sometimes broken. The direction relies on these micro-variations. For example, a faster walk shows increased tension. Similarly, a way of standing back from a crime scene highlights caution. Finally, a trembling hand on a file reveals hidden emotion. It is through these subtle shifts that the series tells the story of Gabrielle’s trauma and gradual reconstruction.
Around her, a solid cast adds depth to the narrative: Hubert Delattre as a police commander torn between loyalty and concern, Nicole Calfan in the role of an influential local figure, Tom Novembre and Lannick Gautry as members of a family with a troubled past, or Amelle Chahbi as a more rational colleague. This gallery of characters helps blur the lines without reducing to a simple whodunit suspect catalog.
A cold staging, anchored in the Grand Est
Visually, Il était deux fois embraces a cold tone. Florian Thomas and Valentin Vincent favor desaturated colors, winter lights, and settings often filmed in wide shots. Hotel corridors and residential neighborhoods compose a very concrete landscape. Additionally, riverbanks and empty industrial areas add a slightly offbeat dimension. Thus, reality itself seems to be cracking.
The filming took place in the Grand Est region, with support from the region itself. Moreover, the Grand Nancy metropolis also provided support. Additionally, the CNC contributed to the project’s realization. Pont-à-Mousson, Toul, Frouard, Vandœuvre-lès-Nancy, and the Prémontrés Abbey host part of the scenes. These locations, familiar to locals but rarely highlighted on screen, give the series a precise visual identity, far from the Parisian settings usually associated with France 2’s crime dramas.
Like many recent productions, the choice to concentrate the action on the same territory is strategic. Indeed, filming mainly in natural settings meets economic imperatives. Moreover, it reflects a search for logistical sobriety. The result is a coherent framework, where the topography of the places becomes an integral part of the drama.
A fragmented narrative that divides critics and audiences
Narratively, Il était deux fois embraces great complexity. The episodes alternate between 2013 and 2025. They repeat certain scenes from new points of view. Additionally, they slip in fragments of diaries or nightmares. These are not always immediately identifiable. The viewer is invited to piece together the puzzle themselves, at the pace of revelations and false pretenses.
This ambition has seduced part of the critics, who praise a demanding fiction, far from overly formulaic crime plots. Several media outlets highlight the coherence of the setup with the very subject of the series. The heroine has forgotten twelve years of her life, and she no longer knows if she can trust herself. The confusion felt in front of the screen thus echoes Gabrielle’s own.
But this same fragmented writing also constitutes a friction zone. Some observers point to a rhythm deemed slow in the early episodes. There is an abundance of twists, as well as a subtle use of the fantastic. This can unsettle fans of more realistic crime stories. In the background, it is the very positioning of the mini-series that questions: between criminal investigation, intimate drama, and dark tale, Il était deux fois chooses to remain on a ridge line.
On the audience side, the success on france.tv nevertheless shows the appetite for this type of hybrid narratives. The record start on the platform, before any television broadcast, confirms the success of the mental thriller. This is driven by a strong female figure and finds its place in the offering of French series. This takes place at the beginning of 2026.

France Télévisions offers an editorial presentation of the fiction on its site France TV & Vous. Additionally, a press kit is intended for professionals.
A unique proposition in the landscape of French series
Il était deux fois stands out without overturning the codes of the thriller. Indeed, it combines criminal investigation, exploration of grief, and reflection on memory. The series entrusts the main role to a heroine marked by a double trauma. Indeed, she suffers from the disappearance of her daughter and the loss of twelve years of her existence. Thus, the series bets on contained emotion, closer to intimate drama than mere police entertainment.
The result, sometimes disconcerting, addresses fans of narrative puzzles. Moreover, it also interests viewers sensitive to the portrait of a woman struggling with herself. This phenomenon illustrates an overall evolution of the French audiovisual landscape. Indeed, genre literature and author signatures are taking an increasing place. Thus, they serve to create identifiable fictions. These works are designed to circulate between linear broadcasting and digital platforms. In this respect, Il était deux fois occupies a unique place in the series lineup at the beginning of 2026.
