Now an agent of Interpol undercover, the former Inspector Giraldi, goes to New York to find his friend Salvatore Esposito, aspiring restaurateur in Little Italy, suffocated by debts with the usurers headed by Don Gerolamo. He will remove the gang and assure her of justice, but she will suffer the advances of the Boss's daughter, the ugly Maria Sole.
