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.
