A virus designed to control the burgeoning spider population causes them to mutate into overgrown, venomous killers. A large horde of the spiders take over the small village of Newtown, killing all but two of its residents. Laurence Johnson and Chloe Jones have only been together one night after Laurence parted ways with his wife. They find themselves trapped in the house with no way of escaping. Their only hope is to try and stay alive long enough for the army to intervene. Lorna Johnson is on the outskirts of town with nowhere to go and the spider invasion taking control. Her only hope of survival lies with a team headed up by Doctor Michael Briggs. He has a plan to stop the invasion before it gets out of hand. But he is running out of time and he is running out of allies. If he doesn't move quickly then mankind will face the darkest day it has ever known.
