Eom Joong-ho is a dishonest ex-detective turned pimp who is in financial trouble because two of his prostitution have gone missing. One night he sends Mi-jin, one of his few remaining girls, to a customer. He then realizes that this is the same person who was the last to see his missing girls. Believing that this man is Human trafficking, he goes to look for Mi-jin, contacting his old Seoul Metropolitan Police Agency for help. But they cannot assist because the mayor of Seoul, whom they are guarding, has just been attacked with feces. The police are now preoccupied with a media storm because they have suffered humiliation for failing to protect the mayor.
