Poongsan

Poongsan has the unenviable - and death-defying - job of delivering messages across the North and South Korean border to separated families. When South Korean government agents ask him to smuggle in In-ok, the lover of a high-ranking North Korean defector, into the South, the damsel and rescuer fall in love instead.
