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.

Grace, Karin's mother and an American married to a Dutch husband, has been nervous about this practice from the start. At first she tells herself the space is good for her daughter, but as the hours begin to tick by and the children fail to arrive at their designated campsite, she becomes certain something has gone horribly wrong.

As Karin fights for survival, and Grace hastens to find her daughter, the night culminates in the reveal of a deadly secret--and a shocking confrontation--that will push each of them to her edge.
