The Bergé family, a wealthy family of industrialists from Val d'Aosta, has a secret, and Deputy Commissioner Rocco Schiavone discovers it by chance, realizing that he is receiving a cry of despair from within the family. Chiara Bergé, the young daughter of the family, very popular among her peers, disappears. Her disappearance marks the beginning of a game played on different levels. Schiavone must find out what lies behind the impeccable image of a privileged environment, race against time in a race for life, and illuminate the gray area where crime and business meet.

Meanwhile, the snow continues to fall, in May, in Aosta, worsening Rocco's already bad mood. And a shadow emerges and follows him to strike him where it hurts. Because in the past of the grumpy cop, there is a dark period that appears at every opportunity. Like an unpaid debt. Like a wound that never heals.
