Imagine a late summer night in July, where Lt. Colonel Dan Preston is wrapping up a grueling day at work. But Lt. Colonel Preston's "office" is unlike any other - he's a pilot of the Lockheed U-2 aircraft, soaring above 70,000 feet along the highly fortified DMZ that divides North and South Korea. As night falls, missiles begin to fly. He faces a daunting enemy, fighting to survive alone and deep behind enemy lines. With no immediate help from his country, Lt. Colonel Preston must navigate his way back to safety.
