CNN makes a rare, exclusive journey inside North Korea. With tensions near the boiling point and Americans banned from visiting North Korea, CNN cameras go inside the secretive nation to places few outsiders have ever seen. Correspondent Will Ripley and his team travel from the heavily armed border region near South Korea, deep through the impoverished countryside where blackouts and food shortages are commonplace, along the coast where frenzied missile testing is underway, through the showpiece capital where a growing consumer class is emerging, and ending along the Chinese border as we climb North Korea's most sacred mountain for the first time in CNN history. Along the way, we have conversations with regular North Koreans who've never been allowed to speak with foreign journalists or have met an American before. While always under the watchful eye of government minders, these unprecedented interviews give extraordinary insight into the lives and aspirations of those who live and work under Kim Jong Un's authoritarian regime.
