When a road trip to Scotland goes horribly wrong, a young family have to survive more than just the elements... A year after the death of his wife, Jack takes his two children for a weekend break in Scotland. A snow storm hits the north of England, and gets progressively worse the further north they travel. On an empty road in the Scottish highlands where the snow is deep and the storm is wild, their car breaks down. Secluded and trapped in the storm, they have to try and save themselves.
