Meet Mr. Daddy(2007)

A little girl is reunited with her reluctant small-time criminal father. Jong Dae is a lowlife conman and gangster who lives in a old trailer in a junkyard by the sea. Not exactly ideal father material. He is (understandably) shocked when, while in jail yet again, a social worker visits to inform him that he has a seven year old daughter called Joon (Seo Shin Ae) who has been living in an orphanage and is on her way to America to be adopted. Little Joon desperately wants to meet her daddy before she leaves.
