The Naitō Shinjuku Family, Japan's oldest yakuza group with a long history of family leadership, is headed by its boss, Gunji Washio (Hitoshi Ozawa). His young son, Taiga (Haruto Ochiai), is being trained as the heir by Reiji (Yoshiyuki Yamaguchi), a senior lieutenant. However, unlike his father's bold personality, Taiga is shy and easily upset, making his future as leader questionable. Just when things are uncertain, Gunji’s brother, believed to be dead, reappears and murders him, throwing the family into turmoil. Adding to the chaos, Taiga is kidnapped by a mysterious attacker.
