Season 1

Mélanie Diore has turned her six-year-old daughter Kimmy into an Internet star thanks to her "Happy Recess" channel and its millions of followers. When the child influencer is kidnapped, Sara Roussel finds herself in charge of the investigation. She must dive into a world she knows nothing about, and into the family that seems to have a lot to hide.

After receiving a message from the kidnapper accompanied by a recording of Kimmy's voice, Mélanie publicly reveals her daughter's abduction. In the midst of a media storm, the police continue their investigation. The Diores may have millions of fans, but they also have their share of haters, and the kidnapper could be among them.

The investigation continues. Could the kidnapper be David Bouthier, the former reality TV star who shares a mysterious past with Mélanie Diore? Or Valentin Lavalle, the misogynist released by the police? As media pressure mounts for the Diore family, the arrival of Mélanie's mother Isabelle adds fuel to the fire. As Bruno pulls away, Mélanie turns to Sara for help. The two women grow closer.

Bruno is arrested following David Bouthier's revelations. Mélanie becomes convinced of the guilt of her rival Fabrice Perrot, who is profiting from Kimmy's disappearance. Sara follows this trail while Malik explores the pedophile angle. But the clock is ticking, the police are in a rut, and Sara loses her footing. Back home, Bruno discovers an SD card with terrifying contents in Sammy's room.

Sara wakes up in the police station and finds Bruno and Sammy who have come to give her the SD card. Sara refuses to believe the images she sees. Following the previous day's slip-up, Mélanie complains to Salomé, who pulls Sara off the case. Nonetheless, Sara delves into Mélanie's past and makes a discovery that points her in the direction of Kimmy's kidnapper.

Baptiste and Sara find Kimmy's cuddly toy and no longer have any doubt as to the kidnapper's identity. While Baptiste warns the rest of the group, Sara sets off alone for the Ardennes to look for Kimmy. On the spot, the local gendarmerie organizes a search party. In custody, Mélanie grows impatient.
