After shooting and killing detective Kataoka, Otomo (Kitano Takeshi) fled to Jeju Island under the protection of Korean agent Chairman Jang (Kaneda Tokio). This Yakuza, who was far away from the Japanese underworld, clashed with the young Hanada (Pierre Taki) of the Karabishi-kai because of an incident. At this time, the Karabishi-kai was led by Nomura (Osugi Ren), the son-in-law of the former chairman, and Nishino (Nishida Toshiyuki), the elder of the Wakagashi, did not buy into the account of this amateur boss. Therefore, the resentful Nomura conspired to use this "Jeju Island Incident" to get rid of Nishino and put the blame on Chairman Jang, but it soon turned into a big war to hunt down each other's leaders. During the war, the declining Sanno-kai plotted to make a comeback, and Otomo, who wanted to avenge his younger brother, also came to Tokyo with Ichikawa (Omori Nanto) and others. Otomo, who upholds a righteous heart, will bring a bloody storm to this greedy underworld Shura world... This film is the final chapter of Kitano Takeshi's "Extreme Evil" trilogy.
