The Wild Ones: The Osaka Yakuza War.

Sakamoto Toshiya (Kawahara Hideyuki), a young assistant head of the Yamashinkai, is imprisoned himself after his partner is killed in a feud with the Takahara family. When Sakamoto was released from prison eight years later and returned to the Yamashinkai, the organization was already under the control of the Takahara family and was involved in the sale of shabu, which was a taboo practice. Sakamoto tries to rebuild the organization with Yamahashi and his subordinate, Asada, but the Takahara family spots him and the chairman, Hirano, excommunicates him.
