When they're hauled into the office in the wake of a stupid prank, schoolmates Elliot and Shannon have no idea that hiding the principal's Smart Car in the woods was the least of their problems. As part of their punishment, the pair is tasked to clean up the school boathouse – the same one that's been shuttered for close to twenty years. Should be an easy enough task, they figure: chuck all the broken stuff, organize whatever still works and get the weekend underway. But when Shannon talks Elliot into making a Ouija board, things take a turn for the horrifying. When the pair accidentally unleashes a dark force, they find themselves caught up in a mystery that must be solved if they are to have any hope of escape.
