Upon the death of her abusive father, Grace returns to the derelict coal mining town that she grew up in, only to find that her brother, David, is missing. Deciding to reunite her family, she sets off into the wilderness guided by a strange man from her past, hoping to find a hippie commune that David has escaped to. Along the way Grace is abandoned and injures her leg. Her only hope becomes another lost hiker who is communicating with her via radio. They agree to meet at an identified landmark in the deep forest where he will provide medical help, but as Grace makes her way closer, suspicions grow as to the true identity of the hiker. As her body begins to break down and hope fades, the night time noises grow ever more menacing, the forest birthing a dark presence which threatens to consume Grace.
