The students of Randolph High are on a Halloween night excursion to All Hallows, a small town in the middle of nowhere, as part of their studies. As they learn the history of the town they find out someone is making that history come to life.

As in a real-life headless horseman who may or may not be Jebadiah Jacobus Hallows, the town's forefather and creator, who comes bolting down the road on his jet black, smoke snorting, red-eye-flaring steed, and holding a head in his hand which may or may not be his own.

And that's not the only thing that frightens the students. A satanic symbol keeps popping up everywhere, there's a ghoulishly twisted tree with a dead man hanging from it, and a curse that has the whole town under its spell.

Can the teens figure out who's reliving the three-hundred-year-old curse and break it before anything else happens? Like their untimely deaths?
