Jack Straw
I look nothing like him!
I watched this a month ago. During the Vietnam War, American POWs were kept in the notorious Hoa Lo Prison, dubbed "The Hanoi Hilton". They tell the inside story of how they secretly communicated with U.S. intelligence agents. Any one who watched the excellent Vietnam War series on BBC a while ago will find this just as, if not more interesting. Thoroughly recommend a watch.
