This story reconstructs the hours before 18-year-old Laetitia disappears, her overturned scooter found in front of her house early one morning. While police are certain they've arrested the suspect, they still haven't found Laetitia's body. The drama follows the repercussions on Laetitia's family, above all on her twin sister Jessica (Sophie Breyer), but also on the inner workings of the police force, social services and the judicial system, even on the government.
