Angry sinkholes attack a small, nondescript town, engulfing people and buildings one by one. These ravenous monsters appear without warning, sucking terrorized townsfolk (including a former-porn-star-turned-reality-show-celebrity) into oblivion. Enter a seismological specialist with a secret past, hellbent on revenge. He joins forces with the local sheriff, who is on a personal mission to save his own daughter and town. Can this unlikely duo abort these monstrous cracks of death? Will our heroes survive overwhelming forces of nature with potentially explosive consequences? Can they combat a skeptical mayor with ulterior motives who will stop at nothing to serve his own selfish gains?
