Katelyn Chambers is overjoyed when her boyfriend invites her to a family getaway in northern Vermont. However, her excitement quickly turns to trepidation when she discovers their cabin is located in what is rumored to be a haunted forest-a forest where a monster walks among the trees, always in search of its next meal.

Despite her concerns, Katelyn does her best to enjoy the mountain retreat, even with the eccentric innkeeper that always seems to be watching her, and the screams she often hears coming from the woods at night. But when someone from their group goes missing, it becomes clear that this rural homestead is far more sinister than it first appeared to be.

Unable to call out for help, the group is forced to choose between staying where they have shelter, or entering the haunted forest to seek rescue on foot. Unfortunately for them, they have no way of knowing whether the monster that's hunting them is in the surrounding woods, or if it's been in the house with them the whole time.
