Unforgiven (2012)

Hakuryu becomes a relentless, pure embodiment of vengeance! The mad warrior who stands in his way is Susumu Terajima!! A small rural town is caught in the middle of a conflict: the local Gotoda-gumi versus the Ebisu-gumi, who want to seize land for industrial waste disposal. In this countryside with nothing but hot springs and violence, a lone man suddenly appears. That man is a former Organized Crime Division detective (Hakuryu), whose wife and child were brutally murdered. His life destroyed by the yakuza, he now lives for only one thing—revenge. With a single purpose burning inside him, he throws himself straight into a hail of bullets.
