In Black River, Tennessee, everyone knows the legend of the Bell Witch… and the alleged curse that hangs like a dark shroud over the town. To some, it is just a local tall tale. But to others, it is terrifyingly real. For centuries, four families have been forced into the ritualistic tradition of sacrifice and terror. Every year, a member of each family stumbles upon an antique music box they need to lock before the time is up. And a horrible fate awaits them once the boxes open.
