is a 1977 film directed by Kinji Fukasaku and starring Sonny Chiba and Hiroki Matsukata. Plot Kawada Noboru is a peasant from Mikuni who becomes a yakuza in the Tomiyasu Group in Fukui. He holds a letter from his boss Mr. Yasuhara promising that he would receive control of the security business for the speedboat racetrack in exchange for killing Yamada. When Kawada is released from prison in 1968 and Mr. Yasuhara refuses to make good on the deal, Kawada buries him up to his neck and forces him to relinquish control over the security business of the bike race and speedboat race run by their gang. At a branch office in Tsuruga, Yasuhara asks for help from the Kanai Group, a destructive yakuza organization based in Osaka working under the umbrella of the Asada Group. Their leader, Kanai Hachiro, sends an excessive amount of 50 assassins to kill Kawada and Mantani warns Yasuhara that this is part of Kanai's plan to invade and destroy Fukui. Kawada hides out in the Shiranami House with his lover Nakai Kiku, who works there. Mr. Yoshitama from Kyoto acts as a mediator and arranges a meeting between Kawada and Mr. Kubo, who has been sent by Mr. Okano of the Asada Group to offer support to Kawada in any battles with the Kanai Group, but Kawada is unreceptive. Kawada is attacked in a diner but the police arrive and stop the fight before he is killed, leaving him seriously injured. Yasuhara appoints Mantani as underboss of the Tomiyasu Group and tells him to take care of Kawada. Mantani is Kanai's sworn brother, so Kawada sees this as another means by which Osaka seeks to control Fukui. Kiku's younger sister Nobuko and brother Takashi, a yakuza in the Yanaka Group in Kanazawa, take Kawada to their hometown of Wajima to recover. Takashi's boss Oya fears that the Kanai Group will invade if they learn of this, so he tells Takashi to move Kawada to a different location.

Kawada attacks the Tomiyasu Group and buries a member up to his neck until he reveals that Mantani is currently at a gambling house run by the Yoshitane Group in Kyoto.
