Joong-ho is a dirty detective turned pimp in financial trouble as several of his girls have recently disappeared without clearing their debts. While trying to track them down, he finds a clue that the vanished girls were all called up by the same client whom one of his girls is meeting with right now.
This movie contains 2 potentially triggering events.
While it isn't violence between partners, a lot of the violence in this movie is centered around violence by men against women. Specifically, violence towards sex workers from their clients.
The general plot of the movie revolves around prostitution, but there are no sex scenes. Mostly just explicit dialogue and some pictures of topless women.
A man throws his feces onto another man's face early in the movie (and then this is mentioned repeatedly throughout the rest of the movie), and later a boy that has been lobotomized wets himself.
No, but there is a lot of head bashing with hammers, chisels, fists, etc. Most (all?) of the deaths in the movie are from blunt force trauma to the head.
