Surprisingly involving. Wonder what happens to N Korean defectors who run over to China and S Korea? This is a not so happy story about some defectors. For reasons that will be revealed later. Things start off with a teen going to S Korea to see his mother who is there now. Can't they make phone calls from China to S Korea? He's resentful but things get interesting and quite sad when the back story is revealed from the mother and then the father's point of view.

Jang Dong Yoon is quite a versatile actor. The more distinctive faces like SJK or LMN or PBG would not have been right for a role like this. Lee Na Young looks quite downtrodden. The ending isn't too sad though after all that's happened before. But would have liked a bit more explanation about what happened during those 5 years.
