Air Force Airman Bryce Callahan reports to the missile silo base in Cheyenne, Wyoming, to take up duties with the Base Security Police Squadron. There he meets Sergeant Todd Claymore, his training partner... who becomes his romantic partner, as well. Their lives settle into a routine as peaceful and pleasant as is possible while they're on active duty.
That peace is broken when a squad of rogue Soviet commandos cross the U.S. border headed straight for Callahan's base, intent on destroying the ICBM missiles. Led by a Soviet general who controls an unsanctioned missile base in the Ural Mountains, the guerrilla action could easily explode into World War III. Caught up in the danger, Callahan and Claymore must face the enemy with courage to stop the attack and an all-out nuclear war.
