Once close friends, Stealth bomber pilots Vic Deakins and Riley Hale become engaged in an explosive battle against time, and each other. In the air and on the ground, in planes, on the tops of trains, and clinging to careening Humvees, theirs is a no-holds-barred race to recover a stolen nuclear weapon that threatens a major American city. National Park Ranger Terry Carmichael must guide the grounded and stranded Hale across the demanding desert landscape--and ends up fighting beside him against an unimaginable menace.
