Birthed from the deep dark bowels of the earth, arachnid-like creatures swarm out of the eruption. A washed-up, former A-list action star, Colton West, suddenly finds himself in a real life catastrophe as he's forced to use his onscreen character training to save the entire city from being victims to the most horrifying creatures imaginable.
