The film begins with a sumptuous banquet at the opulent estate of the Grand Yakuza leader Sekiuchi (Soichiro Kitamura), boss of the Sanno-kai, a huge organized crime syndicate controlling the entire Kanto region. He has invited the many Yakuza leaders under his control. After the formal conclusion of the banquet, Kato, the chief lieutenant of Sekiuchi, pulls one of the Yakuza leaders, Ikemoto, aside and makes plain that he is displeased with the news that Ikemoto has become friendly with a rival gang leader, Murase, while the two were unexpectedly imprisoned together. Kato, underboss of the Sanno-kai, orders Ikemoto to bring the unassociated Murase-gumi gang in line, and Ikemoto immediately passes the task on to his subordinate Otomo (Beat Takeshi), who runs his own crew.
