"Today, there are an estimated 250,000 North Korean refugees living underground in China. They escaped a food crisis and other persecutions at home that have claimed the lives of approximately 3 million in the past 10 years. The Chinese Government -- in direct violation of international laws to which it's a party -- systematically arrests and forcibly repatriates hundreds of these refugees each month. Defecting from North Korea is a capital offense, and repatriated refugees face human rights abuses ranging from concentration camps and torture to forced abortion and summary executions. For a lucky few refugees, however, there is hope. A group of multinational activists has taken it upon themselves to create an Underground Railroad. Via a network of safe houses and escape routes, the activists -- at great personal risk -- help the refugees on daring escapes to freedom over hundreds (and sometimes thousands) of miles of Chinese territory"--Producers.
