Vincenzo flees to Seoul and sets out to recover gold bullion worth ₩150 billion ($110 million), that he helped his business partner (a recently-dead Chinese tycoon) secretly stash within a hidden basement under Geumga Plaza, a commercial building in South Korea.

Unwilling to let the gold to fall into the hands of Babel Group, Vincenzo must use his skills to reclaim the building and recover his fortune.

Among the quirky tenants at Geumga Plaza is the Jipuragi Law Firm run by Hong Yoo-chan (Yoo Jae-myung) in which Vincenzo finds he has aligned interests.

It is revealed that Hong Yoo-chan is killed because he managed to discover that Babel Group is a shell company for a drug cartel and left some clues for his daughter and Vincenzo to find.

Aside from the gold, he stumbles upon a USB left behind by his deceased business partner called the Guillotine file containing incriminating pieces of evidence against Korean politicians, civil servants, and the Babel Group.

As both the corrupt politicians and Babel Group find out about the Guillotine file, they seek to obtain and destroy it while Vincenzo dodges their attacks by staying several steps ahead of them.
