In BORRASCA, Sprouse stars as Sam Walker, who moves to the town of Drisking, Missouri one summer and quickly befriends two other kids, Kyle and Kimber. They take a trip to a strange treehouse, where you are supposed to carve your name on the tree or “you’ll disappear”. When Sam’s sister, Whitney, actually does disappear a few months later, he passes five lonely years wondering what happened to her. When more people start disappearing suddenly, the three take it upon themselves to find out what’s happening to all the disappearing people and what connection the disappearances hold with the mountain outside of town.
