The untold story of the most important rescue mission not just of the Vietnam War, but the entire Cold War: one American aviator, who knew our most important secrets, crashed behind enemy lines and risked capture by both the North Vietnamese and the Soviets. One Navy SEAL and his Vietnamese partner had to sneak past them all to save him.

At the height of the Vietnam War, few American airmen are more valuable than Lt. Colonel Gene Hambleton. His memory is filled with highly classified information that the Soviets and North Vietnamese badly want. When Hambleton is shot down in the midst of North Vietnam’s Easter Offensive, US forces place the entire war on hold to save a single man hiding amongst 30,000 enemy troops and tanks.

Airborne rescue missions fail, killing eleven Americans. Finally, Navy SEAL Thomas Norris and his Vietnamese guide, Nguyen Van Kiet, volunteer to go after him on foot. Gliding past hundreds of enemy soldiers, it takes them days to reach Hambleton, who, guided toward his rescuers via improvised radio code, is barely alive, deeply malnourished, and hallucinating after eleven days on the run.
