Lucia, 17, is escorted by the police to a child and adolescent psychiatric unit that she knows well after several admissions. There, she finds her friend Eloïse, who has been hospitalised for a long time, as well as Yasmine, Camilia, Ulysse and André, each marked by their own journey. Amid care, listening and the tensions of an overstretched ward, the group’s fragile balance is shaken by the arrival of the mysterious Enzo.
