Sad Vacation (2007)

Kenji Shiraishi is involved in the trafficking of illegal immigrants from China to Japan. One such case leaves an immigrant child to be an orphan. Instead of selling him along with others that arrived, Kenji flees with the boy to look after him and make an attempt at everyday life. The people after the boy, unexpected encounters with long-lost family members, and his vengeful nature are standing in the way of his future.
