It is Christmas Eve, and the detachment of a massive avalanche isolates the Vanoi Valley, preventing rescue through the only pass leading to the valley. The village is cut off, the electricity is out, and communications are interrupted. The guests of the luxurious hotel in the small, exclusive ski resort find themselves cut off from the world. While waiting for help, with no way to communicate with the outside world and facing dwindling supplies, they will soon discover that this is just part of a more complex ticking time bomb that could explode at any moment.
And there is also a murderer. The guests and the residents find themselves living a unique experience that will force them to confront themselves and each other: they can only emerge if they overcome their fears, their prejudices, and learn to be a community.
