The dead body of 15-year-old Sara Damiani is found in a flooded basement. Her father, Giancarlo, receives the news while at a television studio where he is about to broadcast a national plea for help regarding his daughter's disappearance. In the homicide division of Turin's police force, Chief Inspector Valeria Ferro grabs the reigns of the investigation.

However, Guglielmo's three children seem to be hiding something; Leonardo works in the family bank, Eva is a suffering artist, Filippo is an eternal teenager… not one of them seems particularly distraught.
