Du-seok (Sung Dong Il) and Jong-bae (Kim Hie Won) are tough-rough private loan sharks who chase down a debtor to collect but end up taking Seung-yi (Park Soi), a 9-year-old girl, as a pawn. Du-seok and Jong-bae promise to watch Seung-yi until she gets adopted by a nice, rich family. But when they later realize that Seung-yi has been sent to the wrong place, Du-seok and Jong-bae bring her back home. Although Du-seok and Jong-bae are stuck with a child they didn’t bargain for, and Seung-yi is left with them as a pawn out of debt, a special bond forms between them.
