Korean Movie: The Chaser DVD Based on a real-life case from 2009, "The Kang Ho-soon Serial Killer Case" is fully adapted into a movie! It's a dual personality role, which is hard to imagine from the now kind and strong Ma Dong-seok, everyone's favorite. It's a work from when he was still a young Ma Dong-seok, and it's rare now! It's a rental return, but it's in good condition with little wear and tear.
