In 1995, seventeen-year-old Tatiana mysteriously disappears near the Perpignan train station, leaving her family in anguish and confusion. Three years later, in 1998, the mutilated body of a young woman, Leïla, is found near the same station. Flore, a young investigator, joins the judicial police team and faces her first homicide case. Tatiana's mother, Marie-José, has embarked in a relentless quest to find her daughter, while the police team, led by Vidal and Sabueso, works to track down the killer. The connection between the two cases remains tenuous, but an unsettling figure begins to draw their suspicion. (thetvdb.com)
