A case of food poisoning derails a family’s holiday and forever alters the course of their lives. Years later, the couple go camping again, looking for one last chance to go back to the way things used to be. But what once was is lost, and they 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 the past and fight for their lives — over and over again.
