I've been searching for this movie in a while and finally got to see it. It's amazing. I love it. At the beginning I was lost, but 20 minutes after it turns good. Is kind of bloody in some parts, but still is good. You can related to Gong Yoo's movie Dogani/ The Crucible. They have like the same problems. You can see how cruel people could be and the consequences it brings. Worth watching.
