A blizzard is slamming into Vermont, but it doesn't matter to Meg Clark. She knows she'll be trapped in her music store in the shopping mall overnight with a small crew of her employees doing one final inventory.

But after they're locked in for the night, they realize this isn't a normal winter storm. Ghastly faces appear in the store windows and disappear in a swirl of wind-blown snow. Dark, mysterious figures loom in and out of sight in the darkened corridors of the mall. Ghostly voices shriek inside the howling blasts of winter wind. Soon Meg and the others are besieged by something too terrifying to imagine.

Before the night is over, a terrible secret from Meg's past will come back to haunt her and the group's only chance to survive will be to go out into the raging storm that's trying to kill them...
