A relaxing retreat into the New England mountains turns into a terrifying encounter with the unknown in this film inspired by one of America's most notorious hauntings. As little girls, Kayla and Jessie loved nothing more than to spend their summers at their grandfather's remote mountain college. Fifteen years later, both sisters are looking for a break from their busy lives in New York City when they decide to return to the place where they made so many good memories. But they won't be alone out there in the wilderness, because Kayla has invited her boyfriend Dean and his pal Tobe along for the trip as well. But when the group experiences a freak fishing accident that leaves them stranded in the deep woods, they quickly discover that these deceptively serene mountains harbor a dark secret.
