1950. In Hiroshima's Kure City, ambitious yakuza soldier Makio Miyoshi (Bunta Sugawara) botches an attempt on the life of a rival boss, and is sent to prison for eight years. In the interim, his Yamamori gang benefits from the country's newfound prosperity and extends its underworld power. When he's released, Makio must mediate a split between the boss and his own bonded brother, Aoki (Tomisaburo Wakayama), which threatens to erupt into violence at anytime, even though Makio longs to embark on a more stable life with a beautiful, ethnically-Korean hostess (Reiko Ike) who's fallen for him. But when Boss Yamamori (Nobuo Kaneko) begs him to kill Aoki, Makio is faced with a crisis of honour which calls into question his loyalty to the gang. Kinji Fukasaku's immediate follow-up to his immensely popular five-film series is a darker, more violent re-telling of the original story, with a new cast of characters fighting to reach the top of the crime world of postwar Japan.
