After an international auto theft sting, major crimes detective Do-cheol is treated to a night at an exclusive club where he is introduced to Sunjin Group's third-in-line, Tae-oh. Animosity quickly arises between the two as Tae-oh's rude behavior rubs Do-cheol the wrong way.
Convinced that Tae-oh is a drug addict, Do- cheol tries to investigate, but is stopped by his boss. Meanwhile, Tae-oh runs into Bae, a truck driver who helped Do-cheol with his auto theft case, protesting outside the company headquarters to get his overdue wages. Tae-oh invites Bae up to his office to write him a cheque. But Bae isn't let off easily -- not before he is humiliated and beaten for Tae-oh's amusement. Bae is subsequently hospitalized but his son finds Do-cheol's card and calls for help. Do-cheol feels responsible and decides to get Tae-oh, no matter how much Tae-oh tries to sabotage the investigation.
