Thousands of North Koreans cross the border into China each year looking for safety and find instead a black market in human desperation. Reporter Oliver Steeds travels along the China-North Korea frontier to meet defectors living in hiding, always one denunciation away from arrest and repatriation to a labor camp. He hears from women sold into marriages with Chinese men who treat them as unpaid labor rather than spouses, and from others funneled into brothels by traffickers who exploit their lack of legal status. Steeds also traces what happens to those caught and sent back, describing the punishment regime waiting for them across the border. The film stays close to individual accounts rather than statistics, building its picture of the crisis through the people living inside it: the fear of Chinese police, the impossibility of ever registering a birth or a job, and the calculation every defector makes about whether staying hidden is safer than going home.
