Tainted Badge (2013)

Kazan (Koji Matoba) is a detective in the organized crime division, but he lives by no rules—raiding gambling dens, starting fights during interrogations, and refusing to be bound by the system. Haunted by a past he doesn’t want to face, Kazan continues his reckless pursuit of evil. One day, his only true partner, veteran detective Utagawa (Hitoshi Ozawa), dies in an accident. Left alone, the man who shared no bonds with anyone finds unexpected understanding with an old-school yakuza boss. As Kazan digs deeper into Utagawa’s death and the truth behind an unsolved gang boss murder, he finds himself stripped of his badge, cast out like a man already ruined. With nothing left to lose, this disgraced detective begins a desperate path of vengeance.
