OK, I must admit that I only watched this film because Gary Oldman is my favourite actor. He plays Holtzer, the head of the CIA branch in Tokyo. His team is hunting for a memory stick rumoured to have proof of the corruption of top Japanese officials. They believe it to be in the hands of John Rain (Kippei Shiina), a hired assassin who specialises in making it appear as though his victims have died of natural causes. Unfortunately, the Yakuza are also trying to get their hands on the memory stick and have sent some men after Rain to retrieve it.
