Fifty years ago, in the hot, barren wastelands of New Mexico, the American government tested atomic bombs. Naturally, before they did so, they cleared out any civilians who lived nearby but one group of miners stubbornly refused to leave.
The radiation from the atomic tests turned those miners into deformed mutants. They and their descendants have survived by living in the mines and preying on unwary passers-by, using their victims for food and breeding.
The latest unfortunates to stray into their territory are eight US National Guard trainees, who are being led on an exercise by their sergeant. They’re being trained for mountain warfare, for combat against the Taliban. However, they’re destined to face an enemy even more monstrous and much closer to home.
