Following the disappearance of a family while hiking in the forests of Steelrock Canyon National Park, Dylan Riley, a veteran member of the search and rescue unit, suffers an accident that leaves him alone in the middle of the night and lost in an unexplored zone of the woods that has been closed to the public because of the dangers it may harbor. But ... Is he really alone? Shadows glide through the trees, watching him, while strange whispers accompany his steps like a creepy leitmotiv, and something that has inhabited these woods for eons makes it clear that he is not welcome there.
