On Pine Street, the houses begin to shake. The earth begins to move. The streets crack open and yards split asunder...and rising from subterranean depths far below, a viscid black muck bubbles up and floods the neighborhood.

In it are a ravenous army of gigantic worms seeking human flesh. They wash into houses, they come up through the sewers, through plumbing, filling toilets and tubs, seeking human prey.

Cut off from the rest of the town, the people of Pine Street must wage a war of survival or they'll never see morning. As bad as the worms are, there's something worse—and far larger—waiting to emerge.
