The season premiere features a profile of Ernie Brace, the longest-held American POW of the Vietnam War. Imprisoned by the North Vietnamese for almost 8 years, Brace suffered torture, starvation and more. Former GOP Presidential candidate Sen. John McCain met Brace when the Navy man himself was a POW in Vietnam and in solitary confinement. Though the two never saw each other face-to-face until they were released, they communicated through the walls of their prison. ➡ Subscribe: http://bit.ly/NatGeoSubscribe ➡ Get More Locked Up Abroad: https://on.natgeo.com/2mdU6QB About National Geographic: National Geographic is the world's premium destination for science, exploration, and adventure.
