Domestic terrorists are attacking people in uniform, in the Four Corners area of southern Colorado. The group of misfits target anyone not elected by the people, but that is just an excuse to commit murder and make a name for themselves. Robert Begay, concerned with the events, only wishes to live a simple life on his ranch. Then the terrorists attack a Colorado Highway patrolman, and incur the wrath of Robert, Navajo war veteran and undercover government agent, who was in the police car with the cop, an old friend. Involved against his wishes, and vowing to stop the terrorists, Robert, a seasoned Army officer, enlists the aid of a National Guard group, which includes his Airborne-trained younger brother, on summer maneuvers nearby. Then he and his lifelong friend and fellow veteran, chase the criminals into the lands of prehistoric Indians, in the canyons of the high desert. Drawing on his alto ego, the Navajo hero-god, Monster-Slayer, and using his experiences in Vietnam, Robert duels with the modern day monsters, while fighting the inner demons haunting him since his wounding in a white man's war.
