Turn-of-the-century Naples. Salvatore Ruotolo and his wife are murdered and their bodies are found in different locations. Since the evidence points to a crime by the Neapolitan crime organization, the Camorra, fear and corruption cause serious hindrances to the investigation by police authorities. In charge is a young and courageous judge who, using evidence discovered by chance, tries to reconstruct the story of the double murder. The plot that the judge must unravel is very complicated.

This music filled biopic follows the life of the legendary tenor Enrico Caruso from childhood poverty in Naples to the beginning of his rise to fame.
