Twelve-year-old Karin is blindfolded and dropped into the Hoge Veluwe National Forest with three other children. With nothing but a few basic supplies and emergency food, the children are tasked with working together to navigate one of the Netherlands' most beautiful and wild locations and return to where their families are anxiously waiting. Karin quickly finds herself at odds with two of the older teens, and suddenly looks up to see that the other children have vanished. As Karin struggles against the elements to find her way back, she soon realizes that something far more sinister lurks in the woods.
