The battle gang Yakuza Hitoshi Kamibayashi (Riki Takeuchi) and the brain gang Yakuza Yoshiro Yazaki (Toshihiko Sakakibara) from the University of Tokyo challenge the summit decisive battle of the extreme society.

Yoshiro Yazaki (Toshihiko Sakakibara), who is loved by Misato (Chikako Aoyama), the daughter of Iwami (Akira Nakao), a director of the Kanto Ichienkai, was forced into a difficult position between the Sumida River Association and Iwami. Hitoshi Kamibayashi (Riki Takeuchi), acting leader of the sand group, is approached by Iwami and is ordered to push Iwami in the next presidential election. However, Iwami is demoted by the presidential election due to the strategy of Sunagawa, the parent of Hitoshi. The furious Iwami immediately awakened the Iwami group and declared a full-scale war to the Kanto Ichienkai.

Kanto Ichienkai, the largest Yakuza organization in the Kanto region. The conflict with the Iwami-gumi was won by the activities of Hitoshi Kamibayashi (Takeuchi), acting head of the sand-gumi, and Yoshiro Yazaki (Sakakibara), the chairman of the sand group, and the Ichienkai seemed to have regained peace. However, the lump of the Iwami-gumi war becomes a spectacular revenge drama and attacks the Ichienkai. It started with a proposal by Sakai, the new chairman of the Ichienkai, to return to the Ichienkai, which was split with the Iwami group. The Takayama group, whose leader was killed by the angry party, was furious at this proposal, and left the Ichienkai to collide with the angry party! On the other hand, Hitoshi and Yoshiro will embark on measures against the Takayama group.

Maki Fujishiro (Yoko Natsuki), the leader of the Fujishiro group, who is feared to be a female leopard in the Hokuriku region, appears in the Kanto region with a young head, Akatsu (Hirotaro Honda). She is said to have chased her niece Natsumi (Megumi Kanzaki) who ran away with the money of the group. Hitoshi Kamibayashi (Riki Takeuchi), acting head of the sand group, and Yoshiro Yazaki (Toshihiko Sakakibara), the chairman of the group, will be ordered by the Kanto Ichienkai to help. As the search progresses, Jin gets angry at Akatsu's excessive violent behavior and the tension grows. And the intention of Hokuriku's expansion into the Kanto region, which is behind the incident, becomes clear.

The group that Hitoshi and Yoshiro once crushed after a fierce battle, the angry party. Takeda, a former Black Dragon Society executive who was in the office after the conflict, infiltrated the Black Dragon Society after his release and took the position of executive. At that time, Hitoshi and Yoshiro were following the case where a familiar Sokaiya colluded with a major trading company and embezzled 500 million gold. It was because they were in the Shima of the sand group, and there was information that the general assembly shop borrowed money from the yakuza and was busy repayment. As I proceeded with the investigation, it turned out that the yakuza was the Black Dragon Society. Hitoshi and Yoshiro learn about the existence of Takeda, a former angry party.
