Cool Korean drama about a crooked cop that accidentally runs over a guy and tries to cover it up. There's some pretty decent comedy with him trying to get rid of the body. Then he gets a phone call from someone that says the saw the accident and wants to blackmail the cop. Then things really get interesting.
Some great films coming out of Korea lately.
