When a powerful storm knocks Fly Creek, Georgia's power lines down onto wet soil, the resulting surge of electricity drives large, bloodthirsty worms to the surface and out of their soil-tilling minds. The townspeople soon discover that their sleepy fishing village is overrun with worms that burrow right into their skin. Inundated by hundreds of thousands of carnivorous creatures, the terrorized locals race to find the cause of the rampage before becoming tilled under themselves.
