Former F1 driver Sawamura (Koichi Iwaki) has been immersed in the underworld of Yokohama alongside his partner Moriguchi (Takashi Fuji) ever since he lost his lawyer parents in a yakuza turf war. One day, he receives a contract to assassinate a high-ranking executive of the Seiryu-kai, a major organized crime syndicate. Sawamura successfully completes the job, but an assassin’s hand blocks their path. Behind the job lay a succession battle centered on Seiryukai executive Kajimoto (Minori Terada). With Moriguchi and his benefactor both killed, Sawamura swears revenge against Kajimoto’s faction.
