Plot synopsis: There was once a boy who pointed a gun at his own father—the head of a yakuza group. Shuji (Ryuji Harada) now runs a bar in Minami, Osaka. Having resented being born into a yakuza family, he had long cut ties with that world. But when a fierce conflict erupts between his father's organization, the Tajima-gumi, and a rival group led by Tokuda (Hitoshi Ozawa), who betrayed them, Shuji gets caught in the middle.
