FRONTLINE goes inside Kim Jong-un’s North Korea — one of the world’s most isolated countries. Using undercover footage smuggled from inside the country, and dramatic stories from recent defectors, the film offers a rare glimpse of how some North Koreans are defying authority in a country where just being caught with illegal DVDs could mean immediate imprisonment.
"Secret State of North Korea" on Frontline airs on Thursday, September 4th at 7 pm on channel 3.
