Welcome to Black Springs, the seemingly picturesque Hudson Valley town haunted by the Black Rock Witch, a 17th century woman whose eyes and mouth are sewn shut. Everybody knows that her eyes may never be opened. Because if they are, every living creature in Black Springs is doomed. For years the town has kept itself isolated – and safe. Until the day that, bored and restless, the town’s teenagers film the witch and upload the footage. And when the video goes viral – all hell breaks loose.
