U.S. Marshall, Pete Nessip and his brother, Terry are aboard an aircraft, escorting convicted computer hacker, Earl Leedy to a federal prison. Mid-flight, an apparent terrorist attack results in an on-board explosion, the death of Pete's brother and Leedy's disappearance. Nobody will believe Nessip's implausible theory that the attack was actually a prison break with the participants escaping by parachute 15,000 feet above the ground.
