Don Walter Mezzanotte arrives in the city of Fontebianca with the proposal to save the poor neighborhood of Borgomale. He immediately realizes that it is not an easy task, but the priest is not the type to be discouraged and immediately gets to work. But he soon realizes that, while he tries to help the poor people, the city hides a dark side that could endanger his life and the lives of others. In this fascinating city the threat of getting hurt does not only come from the hands of people with a black heart, but also from someone who has cultivated an intense resentment for years. Don Walter knows that it could end badly for him, but with the faith of the Lord and a good dose of punches and slaps, he knows he has a better chance of surviving.
