While Hirokazu (Hitoshi Ozawa) has retired from the yakuza life and Ryuji (Yasukaze Motomiya) is serving time in prison, the Miyachi-gumi—where Ryuji once belonged—falls apart. After his release, a boss who leads a fiercely militant faction of the Yamaga-gumi approaches Ryuji. Tasked with putting his life on the line for the Yamaga-gumi’s expansion into Tokyo, Ryuji throws himself into the fight once more. But true to form, his reckless, headlong style only leads him further downhill. Unable to watch any longer, Hirokazu makes a decision—to step back onto the path of blood and violence once again, solely to support his younger brother.
