Elin and Tobias are a happily married couple who regularly vacation with their young daughter. The family is on a dreamy holiday when an innocuous case of food poisoning derails their plans and forever alters the course of their lives. Three years later, the once loving couple is on the road again to go camping, looking for one last chance to go back to the way things used to be. But what once was is lost, and our characters instead find themselves having to relive the same nightmarish events, as that day and the horrors it brings repeat themselves infinitely. Together, they must overcome their trauma, reconcile with their past and fight for their lives. Over, and over, and over again.
