A bar brawl accidentally exposes his true identity as the supreme Don of the underground world, but Isabelle, disdaining him as powerless, files for divorce and moves on to another lover. At a corporate dinner, Enzo sheds his disguise—prompting a host of crime lords to bow before him.

In the end, Enzo decides to attend the Corleone family gathering to settle the marriage agreement, officially announcing the return of the king of the underworld.
