In an age where the Anti-Organized Crime Law has flipped the power balance, even civilians now dare to threaten the yakuza. The Yajima Family is relentlessly harassed by the rising syndicate Shoryukai, yet making the first move would only endanger the organization under the watchful eyes of the law. Their hands are tied. However — one man refuses to abandon the path of ninkyō, the chivalrous code of the yakuza. Acting lieutenant Nagata (Hitoshi Ozawa), who has held the Yajima Family together all this time, chooses to cut ties with his own clan — declaring himself “expelled (hamon)” — in order to strike back and protect the family from the outside. A lone wolf, cast out… but his counterattack is just beginning.
