Go undercover with National Geographic correspondent Lisa Ling as she journeys into mysterious and reclusive North Korea. Posing as part of an international medical team, Lisa and her camera crew and reveal the extraordinary, hidden face of this insular, little-known place, from the powerful control Kim Jong II exerts over his people to the military powder keg of life along the heavily armed demilitarized zone. Filmed against the politically charged backdrop of North Korea's nuclear ambitions, inside North Korea is a fascinating search for the truth, and a mutual understanding, inside one of the most isolated nations on earth.
