I had come to the Sino-North Korean border in order to film a documentary about North Korean defectors. Since Kim Jong-un took office, the situation has been dire for those hoping to escape. If they are caught as illegal migrants in China, they will be deported back to the DPRK where they will face torture and imprisonment. Sook-ja had waded across the icy Tumen River several weeks before, carrying a bundle of clothes above her head. She didn't know how to swim and yet she had risked her life in order to find her sister who had disappeared in China. "I came all this way to find her, and... she's gone."
