After a tragic accident at work, all Grady Miller wanted was an escape. He finds it months later with two of his closest friends. Together, the three of them travel south to Prism Lake for the upcoming holiday, where they plan on spending the sunny weekend drinking, grilling, and relaxing.

Because there's something out there besides the cold . . .
Something sinister . . .
