Fifteen-year-old Sarah is at odds with the world. She dreams of leaving Avetrana and her house. It happens on August 26, when she turns onto via Grazia Deledda towards the beach. The destination, however, is not the sea, but a sad fate.

Michele Misseri, Sabrina's father, finds Sarah's phone on the morning of September 29th. While everything feels inexplicable, his confession comes in the middle of a live TV show, and the recovery of the body provides compelling evidence. The case seems closed, but the investigation goes on.
