Julian is an American expatriate who, along with his older brother Billy, runs a Muay Thai club in Bangkok, Thailand as a front for drug dealing. Billy rapes and kills an underage prostitute and is cornered by Thai police. Lieutenant Chang allows the girl's father, Choi Yan Lee, to beat Billy to death in the same room Billy killed the girl. Chang then cuts off the father's forearm for allowing his daughter to be a prostitute. Julian also engages in deviant sexual practices, preferring to be bound as he watches his favorite prostitute, Mai, masturbate; during a session with Mai he has a vision of himself meeting Chang in a dark room, where Chang cuts his hands off.
