The movie starts something like a less hyper-kinetic, more pastiche Dead or Alive: strange underground activities are done while bodies are discovered by police officers. But when a police officer is killed, one Tatsuhito gets involved... and when he discovers that his brother Shihito is also involved, things get bloody quite fast.
An earlier work of Miike's, Shinjuku Triad Society is still filled with his usual in the ol' ultraviolence and sadistic sex acts, though it's not one of his more eclectic or flamboyant pieces. Rather, it's a pretty well crafted bit of pulp fiction, as Tatsuhito digs his way through the underground, a maze that leads him to a gay Triad leader who sells illegally gained body organs from Taiwan and keeps an almost-brothel of young boys (one in particular the character who kills the cop at the beginning). Tatsuhito's brother is getting involved with said society, so Tatsuhito himself is forced to become a dirty cop and use similarly violent and sadistic tactics to penetrate into this sordid realm.
What's mainly interesting about this little bit of work is the relationship Tatsuhito has with his nemesis, Wang. Tatsuhito is a Japanese born in China, later moved back into Japan, and alienated for it. Wang is a Chinese who felt alienated in China, so killed his father and developed a crime wing in Japan. Wang also is a surprisingly Shakespearian character, which is weird enough as it is, much less that you actually begin to feel sorry for him by the time his ultimate showdown with Tatsuhito comes to be. And Tatsuhito himself is a similarly tragic figure when he's forced to contend with his lack of ability to control his brother. While it would be rude to state that Miike's movies are successful mostly on their shock value, it is true that sometimes it's easy to lose track of how well Miike can create bitter, dis-impassioned characters.
