Only God Forgives

Julian is an American expatriate who, along with his older brother Billy, runs a Muay Thai boxing club in Bangkok, Thailand, as a front for drug dealing. Julian is quiet and seems to have a troubled past. He engages in deviant sexual practices, preferring to be bound as he watches his favorite prostitute, Mai, masturbate. One night, Billy rapes and kills an underage prostitute and is cornered by Thai police. Lieutenant Chang allows the girl's father, Choi Yan Lee, to exact his vengeance on Billy however he sees fit. Choi chooses to beat Billy to death in the same room Billy killed the girl, but Chang later cuts off Choi's forearm for allowing his daughter to be a prostitute in the first place. During a session with Mai, Julian has a vision of himself meeting Chang in a dark room, where Chang cuts his hands off.
