It hadn't rained in months in the isolated quiet town of Garmella, Arizona where cell phones are forbidden. And rain wasn't in the forecast.

Then one June night, a day after the opening of a massive sinkhole at the town's edge, torrential rain descends on Garmella.

The rain brings relief to the town, but that's not all that comes with the rain.

By morning, an ancient evil has consumed the town. An evil responsible for countless deaths and disappearances over the centuries.

Now, Ramon Thomas, sheriff of Garmella, and his deputy Allie, as well as a small group of survivors, must confront the evil before it spreads beyond Garmella to the rest of the world, threatening the destruction of civilization.
