John Rain wants only one thing: to get out of the killing business. However, due to his extraordinary skills, no one is willing to let him simply walk away. His discretion, reliability, and unique talent for deaths from "natural causes" are just too valuable. When an old adversary from the ranks of the Japanese police offers him a new job - to eliminate Murakami, a killer even more fearsome than Rain himself - he knows he cannot refuse. With the help of a painfully beautiful half-Brazilian, half-Japanese stripper, whom he should never trust, Rain tracks his target into the realm of organized crime. Through hostess bars and illegal fight clubs, where only the strongest survive, he finds himself at the heart of the shadow war raging between the CIA and the Yakuza.
