La Compagna di Classe

Nik, after the sudden departure of his son Gus, is left alone. He sleeps in his son's bed, without touching anything in his room. He also regularly charges the battery of his son's cell phone, that has been quiet for the past three months; one night, all of a sudden, the cell phone receives a text message from Adele, a Gus' old classmate, who just came back to Italy and who thinks he is still alive.
