Four girls, who have been friends for years, rent a cottage in the Ardennes during the Christmas holidays. They quickly find themselves snowed in. There is no electricity, the mobile network is down and the nearest house is miles away. The girls aren’t worried at first and laugh about their situation until Kim disappears after an argument. Soon after that, Faye goes missing too. Concern quickly turns to fear when Abby and Pippa spot a trail of blood in the snow. Do the girls really know each other as well as they think?
