Welcome to the Blackwater Fossil Preserve. The apex hunters of the past are no longer history and the containment grid just failed.
Paleobiologist Tessa Harlan knew resurrecting the ancient beast was a catastrophic mistake. The thousand pound reptile is not a slow river dweller. It is an armored and fully terrestrial pursuit hunter with interlocking tusks and terrifying speed.
When a massive Gulf Coast storm floods the preserve and kills the power the grand opening turns into a slaughter. Trapped behind high concrete walls with a sinking escape route Tessa and a small group of tourists must outrun a relentless pack of ferocious killers.
They are trapped in the ultimate nightmare. The hunt has begun.
