Plot synopsis: Nishinari, Osaka— Katsuhiro Tokuyama (Ryu Gan), who had been living as a civilian, gives in to repeated pleas from his former comrades and revives the delinquent gang Tokuyama-kai. The Tokuyama-kai begins seizing territory one after another from local yakuza groups. However, a clash with Nishinari’s largest prostitution syndicate, Shiraku-kai, becomes inevitable. Shiraku-kai retaliates by murdering one of Tokuyama-kai’s members, Shinjiro Nakanishi (Kyosuke Yabe), and kidnapping Katsuhiro’s only son, Nishiki. Swearing vengeance for Shinjiro and the rescue of Nishiki, six men arm themselves with Japanese swords and head for the Shiraku-kai headquarters. Waiting for them are 100 elite swordsmen, the Shiraku-kai’s fearsome “Batto-tai.” Six against one hundred. The curtain rises on a brutal, fearless battle where death holds no meaning.
