Anzai Takashi (Koichi Iwaki), the leader of the Anzai-gumi, enjoys poker at the Kishochokai’s underground casino. Meanwhile, a heated poker duel unfolds between female gambler Himiko (Sayaka Tsuruta) and university student Kota Katori (Shota Haruta). Kota loses, wiping out ¥2 million. Tokunaga (Masami Tate), a half-gangster, schemes to clear his ¥5 million debt by using Kota in a rigged game but gets caught, increasing his debt to ¥7 million. The next day, Tokunaga disappears, leaving Kota to shoulder the debt. Desperate, Kota’s girlfriend, Anna (Mari Yamaji), returns to her family home and explains the situation to her mother, Reiko. Seeking help, Reiko turns to her husband, who is none other than Kawabe Akira (Yoshiyuki Yamaguchi), the Anzai-gumi’s second-in-command.
