Lee Know was the most wanted mobster by the Seoul police, with several cases of drug trafficking, murder and more on his criminal record. Someone who really needed to be careful with. You worked in the police, and were summoned to continue the search for Lee Know. His team went to a specific location, an old building, where his notes said he passed by there.

Your vision suddenly failed, a thick cloth was placed in front of your nose and mouth... Making you pass out, and wake up in a place completely unbeknownst to you.
