In 1967, US Air Force fighter pilot James Shively was shot down over North Vietnam. After ejecting from his F-105 Thunderchief aircraft, he landed in a rice paddy and was captured by the North Vietnamese Army. For the next six years, Shively endured brutal treatment at the hands of the enemy in Hanoi prison camps. Bound in iron stocks at the Hanoi Hilton, unable to get home to his loved ones, Shively contemplated suicide. Yet somehow he found hope - and he became determined to help his fellow POWs survive.
