Lucia, 17, is brought by the police to the adolescent psychiatric ward in a public hospital, a place she knows all too well. Back inside, she reunites with her friend Eloïse, who is hospitalized long-term, and meets a new group of teenagers, each wrestling with their own struggles. Led by Etienne, the team of doctors treats, listens, and meets with families as they confront the raw realities of their patients’ lives, all while managing an overstretched department. Fragile bonds form between patients and caregivers, creating a delicate balance that offers glimpses of hope, recovery, and even laughter. But one day, the arrival of a mysterious new patient named Enzo threatens to turn everything upside down.
