Four caravans, four families inside waking up to a horrifying new reality. They, their cars and caravans, even their pets, are no longer where they were located when everyone went to bed the night before. It seems that their world has somehow moved on, taking them away from their Swedish holiday camping ground to a new place that only superficially resembles where it is that they came from. Acres and acres of grass that is yet not grass. An endless sky, and the frustration of having no landmarks in a sterile and unpopulated landscape. But is it truly empty?
Rather than banding together for the common goal, it seems at first that the families are in denial. Not everyone, but then there are small children to consider. Life of a form will go on. Escape seems impossible from an environment where not even their navigation systems can detect their true location. When the dead begin to seek them out and someone in their own group seems set on sabotage, it is hard for the holiday makers to decide who or what might be the bigger threat.
