After their mom dies of cancer, Shane and Aimee Lancaster's dad decides it's best for the family to leave Boston and make a new start elsewhere. He accepts a job in the small town of Sleepy Hollow, New York. But from the time the Lancasters arrive in town, strange things begin to happen, events that seem to have no explanation outside the supernatural. Sleepy Hollow has always been a town of legend and myth, but now it seems that those legends are coming alive. And when an apparently headless horseman begins murdering people in town, Shane and Aimee begin to fear for their lives. The two teens decide to try and uncover the truth, even though the adults insist it must be an ordinary murderer dressed up as the horseman.
