Hanoi Hilton

S1 E3: The Hanoi Hilton is perhaps the most famous American POW prison of the Vietnam War located in the city of Hanoi. In Vietnamese its name literally means "hell hole" but even hell cannot break the will of some American POWS like John McCain, the hero who endures years of torture, or the group of airmen who invent a secret communication code to talk to each other, and Jerimiah Denton who sneaks messages home on live TV.
