The Sanno crime family has grown into a massive organization dominated by young executives whose new approach to running the family is causing frustration and pent-up resentment with the old-guard members. This vulnerability in the Sanno hierarchy is exactly what detective Kataoka has been looking for.
Kataoka wants a war between Sanno and the neighboring Hanabishi crime family so they destroy each other. His trump card is Otomo (Kitano) - the rumored-dead boss of a defunct family that was destroyed by the Sanno, who has just been released from prison.
Otomo wants to retire from a life of crime, but finds himself drawn back in through Kataoka's manipulations as the Sanno and Hanabishi clans teeter on the brink of an all-out war.
