The Headless Horseman is back! A gang of middle school misfits. An occult ritual. A legendary spirit from America's past. What could possibly go wrong? On Halloween night, Derek Houseman, recent arrival to the Sleepy Hollow region of upstate New York, joins a group of classmates for an evening of trick or treating. They also have plans to perform a ritual that's gone viral online. A ritual that just might work ... When the Headless Horseman rises from the grave for his annual ride across the countryside, empowered by the gang's spiritual meddling, it's up to Derek and the rest of the Sleepy Hollow Gang to stop him. Can they survive the night or will they lose their heads?
