A group of young adventurers go to the snow-capped mountains of Massachusetts, but by the will of fate they find themselves in a mysterious forest. Something strange and sinister is going on here. Young people try to escape, but it is not so easy to get out of this mystical place. Once upon a time, witches lived here, and evil spirits densely enveloped the thicket. Something to hunt people, takes possession of them and, it seems, will not stop until it exterminates all life in this cursed forest.
