The Yamazaki family is seriously dysfunctional. Dad was a TV reporter until he got fired for airing footage of his own humiliation by a group of street-toughs. He's trying to win his job back by secretly filming the high-school bullies who daily beat up his son Takuya. Takuya takes out his frustrations on Mum by beating her up when he gets home ("No, not my face! Don't hit my face!"), and she gets into heroin to assuage her pain. Meanwhile daughter Miki has left home to become a hooker. But everything begins to change the night Dad comes home with a mysterious stranger.
