Dink, Josh, and Ruth Rose are spending Halloween in Sleepy Hollow, home of the legendary Headless Horseman. They are going to sleep in an old cabin, take a haunted hayride, and check out the Old Dutch Church. That's where some people say they've spotted the ghostly horseman. But strange things start happening that don't seem to be part of the planned spooky fun. Is there a real Headless Horseman haunting Sleepy Hollow?
