As Japan gears up for the 1964 Olympic games, the cops start to crack down under pressure from the public and the press, adding a new dimension in the war for power among the yakuza families of Hiroshima. Akira Kobayashi's Takeda tries to keep a lid on things, but hotheaded underlings create chaos, with one boss whacked in neutral territory, and the craven boss, Uchimoto, informing on an assassination attempt by his own minions. While the police round up hundreds of yakuza foot soldiers, Bunta Sugawara's Shozo Hirono plots to finally take out longtime nemesis, boss Yamamori.
