When astronaut Spencer Armacost returns to Earth after a mission that nearly cost him his life, he decides to take a desk job in order to see his beautiful wife, Jillian, more often. Gradually, Jillian notices that Spencer's personality seems to have changed, but her concerns fade when she discovers that she's pregnant. As Jillian grows closer to becoming a mother, her suspicions about Spencer return. Why does it seem as if he's a different person?

Hick handymen Val McKee and Earl Bassett can barely eke out a living in the Nevada hamlet of Perfection, so they decide to leave town -- despite an admonition from a shapely seismology coed who's picking up odd readings on her equipment. Before long, Val and Earl discover what's responsible for those readings: 30-foot-long carnivorous worms with a proclivity for sucking their prey underground.
