Running from a life she didn’t choose, in a city she doesn’t know, Sukanya, a young Thai girl, loses herself in Tokyo. With her Bangkok street smarts, and some stolen money, she stays ahead of her former captors willing to do anything to recover the computer she took. After befriending Chiho, a Japanese girl living in an internet café, Sukanya makes plans to rid herself of her pursuers, and her past, forever.
Meanwhile, Detective Hiroshi Shimizu leaves the safe confines of his office to investigate a porn studio where a brutal triple murder took place. The studio’s accounts point him in multiple directions at once. Together with ex-sumo wrestler Sakaguchi and old-school Takamatsu, Hiroshi tracks the killers through Tokyo’s teen hangouts, bayside docks and crowded squares, straight into the underbelly of the global economy.
As bodies wash up from Tokyo Bay, Hiroshi tries to find the Thai girl at the center of it all, whose name he doesn’t even know. He uncovers a human trafficking ring and cryptocurrency scammers whose connections extend to the highest levels of Tokyo’s power elite.
