Yakuza Graveyard

Tormented by guilt and embroiled in a leteral dead-end affair with a woman he widowed in the line of duty, renegade Detective Kuroiwa (Tetsuya Watari) is the one-man definition of rogue cop. When his corrupt superiors assign Kuroiwa to the organized crime beat, they inadverently pull the pin on a gun-toting human hand-grenade. Violating his hands-off orders, Kuroiwa plunges fists first into the Nishida gang yakuza underworld. And when he meets Keiko (Meiko Kaji), the beautiful half-Korean wife of an imprisoned Nishida boss, Kuroiwa finds himself risking much more than just his badge. (official distributor synopsis)
