An ordinary administrative case: a man has been run over on the highway by a hit-and-run driver. There would be no need for Valeria, but Inspector Ferro understands right from the start that things aren't as simple as they seem.

The investigation is also a chance for her to get away from her family: the last altercation with her mother has left her disappointed and bitter and she wants nothing to do with her anymore. But, after making peace with Lombardi, Valeria returns home to her uncle Giulio, the man who raised her like a daughter.

Giampaolo Petrone, the openly gay owner of a nightclub, is found dead. The man was not in close contact with his family, who had never accepted the fact that he was gay, and so Inspector Ferro begins questioning his circle of friends and acquaintances.
