In Chinatown, law and order is turned upside down when a trio of feral Chinese gangsters arrive, start terrorizing civilians, and usurping territory. The beleaguered local gangsters team up with the police, lead by the badass loose cannon Ma Seok-do, to bring them down. Based on a true story.

After people in his town start turning up dead, a grumpy landlord is visited by a man who recounts an unsolved serial murder case from 30 years ago that may hold the clue to what is happening now.
