This is a strange and super violent movie (its a Korean cop movie and it involves a transgender so what do you expect?). Detective Ji-Wook is like the most kick ass detective ever known to the force. He's a homicide detective who always gets the bad guy. But he secretly is working towards becoming a woman permanently. He resigns from the force so he can become a woman but a criminal syndicate that is looking for revenge and sucks him back into the violence by taking Jang Mi -- who is like his best friend or the person helping him become transgender or something -- as a hostage. It's like a violent Korean police drama meets Beautiful Boxer.
