Kinji Fukasaku, the director of the controversial BATTLE ROYALE, here paints a dire portrait of the corruption that reigns over both cops and yakuza gangs in 1970s Osaka. Kuroiwa (Tetsuya Watari) is a cop whose brutal tactics place him closer in spirit to the criminals he is bringing down than to the law-abiding citizens he's supposed to protect. As the cops attempt to broker peace between two rival gangs and tensions mount in the underworld, Kuroiwa starts to fall for the wife of one of the bosses.
