Julie Castro has been missing for over 8 years. Stubborn and resilient, her mother Suzanne searches in vain for a sign of life. While visiting a patient, she distinguishes Julie's face in the photo of a recent demonstration that appeared in a newspaper in a small town located in Haute-Loire. Going in search of her, Suzanne discovers a community where no one has ever heard of Julie.

Following the discovery of Anaïs' body, suspicion falls on Suzanne. For her, the disappearance of Julie has a direct link with the murder of Anaïs. Gabrielle Varan, a young police captain, is in charge of the investigation.

Following her intimate conviction, Suzanne introduces herself to the town pharmacist, Eric Desner. For the police, everything suggests that he had kidnapped Julie, Suzanne's daughter. Only Gabrielle is convinced that he doesn't fit the profile.

Suzanne tries to get Stéphanie to talk so that she reveals to her where her daughter is being held prisoner. So close to the goal, Suzanne could commit the irreparable to get her hands on her daughter.
