Terrorists are holding America under siege, and their method is as ingenious as it is deadly. Using commercial aircraft purchased from a failing domestic airline, they drop bombs on unsuspecting and critical targets - including the busy airports of Los Angeles and Dallas/Fort Worth. When the nation begins to panic, the President orders Lieutenant General Robert Blocker to reestablish security in the skies before the fallout hits the White House. Blocker's response to the crisis is drastic - until the terrorists strike again in Denver, then Memphis. The deadly game reaches its breathtaking climax in midair dogfights over Washington, D.C., as Blocker battles to stop the terrorists from hunting down Air Force One.
