This movie was the South Korean equivalent of Bourne series here in the US. Dude was a super pimp special ops person turned pawn shop bum. Some druggies started fucking with his only friend, some little girl and Mr. Pawn shop goes all ape shit on everyone.
The final action scene towards the end of the film is one of the greatest knife fights I've seen in a long time.
Movie was dude-tastic!
