Plot Won-ho is a police detective attempting to bring down Asia's biggest drug cartel run by a man called Mr. Lee. He has been seen by no one, and as a result, a lot of drug dealers have been posing as him to conduct illegal trades. One day, when Won-ho is approached by Oh Yeon-ok, who has recently survived an explosion intended to kill her, Won-ho's team arrives at the site and finds a survivor. When he is admitted to hospital and tries to escape in order to find out about the fate of his mom and pet dog, the police catch him and make him speak the truth. He is revealed to be Rak, a former member of Lee's gang. Won-ho takes him to his dog and reveals his mother to be dead, making Rak team up with the police to seek revenge against the boss responsible for his mother's death and dog's poor condition. Rak and Won-ho arrange a meeting with Ha-rim, who poses to be Mr. Lee. While establishing a fake business with him, Won-ho learns his lines and eventually disguises just like Ha-rim, posing as Mr. Lee as Rak arranges a meeting between him and Park Sun-Chang, a criminal aspiring to work with Mr. Lee. Won-ho imitates Ha-rim and tricks Park Sun-Chang into believing he is Mr. Lee. However, Sun-Chang offers him his own drug, and unable to refuse, Won-ho has to snort it. The drug shows its side effects but his team saves him. Won-ho and his team get the drug materials from Ha-rim and Rak takes them to two mute drug makers, Dong-Young and Joo-Young. As they produce drugs, a new criminal named Director Brian comes into play. Won-ho watches him from a distance and discovers Rak's real identity as an adopted child of a family.
