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.
