Highly decorated homicide detective Choi Chang-sik has an enviable record and the respect of his peers. Days before a promotion, he dozes off on his way home after a celebratory drink with his colleagues. He wakes up to find that his taxi driver has taken him to a remote mountain trail and has pulled a knife on him. The two struggle, and Choi manages to kill the taxi driver in self-defense. Afraid that the incident would negatively impact his career, he covers up the crime scene and flees. The next day, the taxi driver's dead body has been strung up on a crane in front of the police station, and Choi is assigned to the case amidst widespread media attention. Choi's ordeal begins as he tries to misdirect the investigation and remove evidence, to the growing suspicion of rookie detective Cha Dong-jae. Then a man claiming to be the killer turns himself in and threatens to reveal the truth unless Choi reopens an old case.

This movie starts off with detective Choi Chang-sik enjoying his possible promotion with his officers. But an old case comes back to him by way of a killer disguised as a taxi driver, tries to kill him. During the ordeal, detective Choi kills the man. He leaves the body where it is a finds his way home. But the next day the body is found swinging from a crane. The station now asks, who is the killer? Detective Choi is thrown into this dilemma with all the evidence pointing to him. But as he tries to clear his name by finding as much evidence linked to him to eliminate. While he is doing this, he finds more and more evidence of his past creeping up on him and having to hide one thing on top of another.

But as all Korean revenge movies come to fruition. The plot that develops shows you the complicated plan by the criminal executing it. I like a good story with the foreshadowing throughout the movie that you can begin to realize as it shows up in different ways in the movie. This was a very good directed, and edited movie. Not very intense as other Korean movies but a good strategic and sad set of circumstances that ends with more sadness for almost everyone that was involved.
