  ## Plot
  
  Seong-beom is a foul-mouthed, hot-tempered detective with uncanny animal instincts in the violent crimes section who has never failed to solve a case. While he is on an undercover operation, he hears that a colleague of his has been brutally murdered by an unknown assailant. Seong-beom and the police agency instinctively know there is something behind this murder case. They set up a Special Investigations Unit (S.I.U.), and profiler Ho-ryong, a former FBI agent, is assigned as Seong-beom's partner. As the police dragnet begins to close in, the suspect is always faster than the police. They then receive a suspicious shoot to kill order from high-ranking police officials once the suspect is found. The team must fight against conspiring powers responsible for the crime, all the while dealing with tension and mistrust that begin to build within the police force itself as more information about the case begins to surface that may implicate corrupt detectives within their ranks.
