On Christmas, during one of the worst snowstorms Indiana has ever seen, five strangers are forced to take shelter inside of a roadside diner. As the night progresses, the snowfall shows no signs of relenting, ice begins to build up on the roads, and the temperature seems to be dropping by the hour. But the worst has nothing to do with the weather, and everything to do with the sixth visitor coming to the diner.

The jolliest time of the year quickly turns bloody as the diners find themselves fighting for their lives. This Christmas won’t just be white. It’ll be red, too.
