As Part II opens, Leo Roland is desperate. His close La Cosa Nostra associate, Ed Clementi, has been subpoenaed by the U.S. Clementi is desperate to get out of the rackets but Roland reminds Clementi of the oath he swore to La Cosa Nostra - the La Cosa Nostra comes before family and all else. Roland is prepared to order a hit on anybody Clementi knows who could be a potential witness. Meanwhile, Clementi's nephew, Paul, the hit man known to the authorities as "Cupid," has committed a potential fatal blunder. The FBI has recovered one of his teeth that was knocked loose by Cupid's last victim. Now, FBI Inspector Lewis Erskine has a way to find who Cupid is and to connect him to Leo Roland. The question is whether the FBI's top investigator can reach Cupid in time before he turns murder into slaughter.
