The film begins with a sumptuous banquet at the opulent estate of the Grand Yakuza leader Sekiuchi Soichiro Kitamura, boss of the Sannokai, 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 orders Ikemoto to bring the unassociated Murasegumi gang in line, and Ikemoto immediately passes the task on to his subordinate Otomo Beat Takeshi, who runs his own crew. Shortly thereafter an incident occurs at a nightclub owned by Murase where a man posing as a customer is inadvertently put through a shakedown for about one million yen. It turns out that this is a member of the Ikemoto family who has been planted into the nightclub in order to help setoff the conditions for an allout gang war against the Murase family. Murase, who is completely in the dark concerning his having fallen out of favor with Sekiuchi, tries to ameliorate the situation by relying on his former prison friendship with Ikemoto, not knowing that Ikemoto is under orders to terminate his gang. He accepts Ikemotos advice several times not suspecting any illintentions from Ikemoto and each time he further weakens his strength, his resources and his crime family. In one incident, Otomo leaves vicious scars on the face of Kimura who is Murases chief lieutenant. When the dust finally settles from the escalated tensions, Ikemoto and Murase are killed, Otomo is in a maximum security prison, unexpectedly with Kimura, and is stabbed twice in a prison ambush by Kimura in the belly with a makeshift knife. The complex interactions in the film finally come full circle and the film ends with Kato secretly killing Sekiuchi and taking control as the new Grand Yakuza leader of the Sannokai organized crime syndicate.
