Shiro Yamada has infiltrated a fearsome Yakuza clan in Tokyo in search of his missing mother, but now both their lives are at stake, unless he's willing to kill a New York City cop. Shiro Yamada's problem has always been his lovely, wayward mum, Siono, who was whisked to her native city of Tokyo from their home in Honolulu, Hawaii by a mysterious businessman. Now she's gone missing and may even be dead, according to a strange telephone call. Scraping together money to fly to Tokyo, Shiro learns that his mum's boyfriend was none other than Shun'ichi Harada, a major Yakuza clan leader. He has no choice but to infiltrate the deadly gang as a low-level bike messenger. He finds out his mother was forced into sexual slavery, but is she dead or alive? Shiro puts his life at risk, and that of a young Yakuza prostitute, Miki, by asking too many questions. The Yakuza have figured out who Shiro is and if he wants to survive, he must travel to New York and eliminate a powerful enemy: Kono Takumi. The man's crime? He is a NYPD detective who infiltrated the Yakuza to solve a murder mystery. Not only that, but Kono is gay, which the clan finds offensive. Unfortunately, so is Shiro. Will he shoot to kill the one man he finds so attractive? Or is this a dangerous game in which there are no winners?
