In a volatile power struggle between rival yakuza factions, the Sanno crime syndicate is in the midst of expanding its influence into Tokyo. With younger leaders displacing the old guard, tension rises within the gang. Detective Kataoka, seeking to exploit these internal conflicts, manipulates events from the shadows to ignite further discord.

Otomo is pulled back into the violent whirlwind despite his desire for a quiet life. As alliances shift and vendettas are pursued with brutal precision, old wounds are reopened and battles rage both within the yakuza and against law enforcement. The ensuing machinations lead to an inevitable clash that will determine the future hierarchy of the underworld, leaving a trail of betrayal and bloodshed in its wake.
