Janet (Erin McGrane) and her children are on the way to the airport to pick up their father (Aaron Laue) when they are forced to take shelter from a tornado that is ravaging the area. They manage to find a storm shelter outside of a seemingly abandoned house, only for the group to become trapped by a fallen tree that prevents them from leaving the storm shelter. Things are made worse when they discover that they're not alone in the house or storm shelter and the group is attacked by a monstrous creature.
