Late at night, local resident Irene is startled by the appearance of a short alien-looking man at her window, followed by beams of light.

Sue Beth brings her classmates, Ginger and Becky, to a native burial ground where they find various animal bones painted and arranged on sticks.

The ground suddenly collapses beneath them, and the girls find themselves trapped in a cavern containing ancient artifacts, hieroglyphs, and skeletons.

Meanwhile, Texas Ranger Phillip Sheraton witnesses the UFO emerging nearby from the woods, and it causes his rifle to disappear in a beam of light.

The townspeople watch as he returns inside his vehicle, which subsequently crashes into the town water tower before exploding.

During the burial, Sue Beth lays the crystal atop the casket, which causes it to glisten and glow blue before it launches into the sky, disappearing in a torrent of light.

[3] Mickey Hays, who was cast in the film in the role of the alien, suffered from progeria that gave him an unusual appearance.
