Due poliziotti che circolano per le strade desertiche del Nuovo Messico, avvisati da un pilota di un piccolo aereo da ricognizione trovano una bambina che vaga in stato di shock con una bambola in braccio e subito dopo una roulotte distrutta con uno strano squarcio fatto dall’esterno, chiamano i rinforzi e un’autoambulanza che porta via la bambina in stato catatonico.
New Mexico State Police Sergeant Ben Peterson (James Whitmore) and Trooper Ed Blackburn (Chris Drake) discover a little girl in shock wandering the desert near Alamogordo, New Mexico. They retrace her steps to a mobile home owned by an FBI Special Agent named Ellinson on vacation with his family. The trailer side is ripped open from the outside; no trace is found of the rest of the family. Only a single, unidentifiable footprint is left behind. A strange, pulsating high-pitched noise comes on the desert wind, and the little girl briefly reacts to it, but no one around her notices.
