On their way home for the Christmas holidays, a father and his daughter, together with other travellers, get trapped in a tunnel. The reason for the incident is a deadly fire caused by a wrecked tanker. It cuts the way out to the unlucky sufferers, giving them little hope to survive. Even with the most efficient organisation and rescuers who are immediately on their way to the disaster location, this is the North. Until the help arrives, each of the people in the tunnel has to find their own way to stay alive. As time goes by, the crisis escalates making it a live or death situation.
