Even for an average citizen, a love triangle is dangerous business. For assassin John Rain — it's going to be downright deadly.

When John Rain, the Japanese/American "contract killer with a conscience," learns that his former lover, Midori, has been raising their child in New York, Rain senses a chance for reconciliation, perhaps even for redemption.

But Midori and the child are being watched by Rain's enemies, and Rain's sudden appearance puts them in terrible danger. To save them, Rain is forced to use the same deadly talents he had been hoping to leave behind. With the help of Tatsu, his friend and nemesis in the Japanese FBI; and Dox, the ex-marine sniper whose good ol' boy persona masks a killer as deadly as Rain himself, Rain races against time to bring his enemies into the open and eliminate them forever. But to finish the job, he'll need one more ally: Israeli intelligence agent Delilah, a woman for whom Rain's hopes with Midori represent an altogether different kind of threat...
