Cut off from the world, survival isn't a plan. It's a war.
When a violent September storm floods the only bridge out of Hollow Creek, operations manager Nora Vasquez and 130 festival guests are left completely isolated without power, phones, or an escape route.
But the rising water is the least of their problems.
Lurking in the rain-drenched shadows is a massive, four-hundred-pound killing machine that has claimed the property as its territory. Cunning, relentless, and unfazed by gunfire, it begins systematically hunting the trapped crowds. As night falls and the death toll rises, the survivors must turn their quaint autumn retreat into a fortress.
With supplies dwindling and panic setting in, Nora and a handful of desperate locals must outsmart an unstoppable force of nature before it slaughters them all.
