After an international auto theft sting, a dimwitted detective Do-chul is treated to a night at a club where he meets Sun-jin Group third-in-line, Tae-oh, whose rude behavior rubs Do-chul the wrong way. Convinced Tae-oh is a drug addict, Do-chul tries to investigate, but is stopped by his boss.
Meanwhile, Tae-oh runs into Mr. Bae a truck driver that helped Do-chul with his auto theft case - and his 9-year old son, protesting to get his overdue wages. After being humiliated and beaten for Tae-oh's amusement, Bae is hospitalized but his son finds Do-chul's business card and calls for help.
Do-chul feels responsible and so decides to get Tae-oh, no matter what it takes and no matter how much Tae-oh tries to sabotage him.
