The best Yoo In-young’s action movies

When an old collaborator gets severely injured, a veteran policeman tries to figure out the way to bring to justice the ultimately suspected aggressor, a spoiled young executive, heir to a mega corporation, who believes he is above the law.

The plot of this film has a young beautiful spy from North Korea going south to capture another rogue spy. She goes undercover at Burger King and soon she's battling with her co-workers for the affections of the local boys, dealing with a culture clash between North and South, and a very cute young man who's posted pictures of her on a website of local "angels" possibly blowing her cover.

Su-hyun wants to leave the syndicate and opens a small restaurant. Helping his life-long friend from an orphanage, he gets arrested for a murder that he didn't commit. To catch the real killer, he hurts himself in prison and is transported to the hospital. Sung-woo is a homicide detective. His wife has left him, and his son's life is in jeopardy. He can't afford to pay the hospital bills, not to mention the liver transplant needed to save his son's life. To make matters worse, he gets reprimanded at work for walking out on his undercover post, which led to the death of his partner. Having gotten drunk out of guilt, he creates a scene at the funeral for his late colleague and gets kicked out, only to end up becoming a hostage of a jail breaker, Su-hyun.
