About the title
A group of friends heads to the countryside for a party. Drinks, a jacuzzi — what more do you need to really cut loose? But the fun comes to an end when a terrible thunderstorm breaks out: lightning flashes everywhere, one bolt frying an unwary guest. The frightened group tries to take shelter from the raging storm in the nearest house. But once inside, they soon realize that the mansion's walls hide a danger no less deadly than the weather outside.
