Plot
In 1954, New Mexico State Police Sergeant Ben Peterson and his partner, Ed Blackburn, discover a little girl wandering the desert in a catatonic state near Alamogordo, and the ravaged and abandoned travel trailer she came from a few miles away. The officers summon an ambulance for the girl, and, while the scene is processed, go to a nearby rural general store. They find it destroyed in the same way as the trailer, and the owner's dead, mutilated body in the cellar. No money was taken at either crime scene. Peterson leaves Blackburn alone to wait for backup, and Blackburn hears a strange, pulsating sound outside. He investigates, and empties his gun at something before screaming in agony.
