An English school teacher outposted in Africa has a run in with the local witch doctor and suffers a nervous breakdown. After recovering back in England she takes a job teaching in a small country town hoping to make a new start for herself. All goes well at first, until she starts to hear some disturbing stories about the town. She soon discovers the town is home to a coven of witches and they plan to sacrifice a local girl in one of their rituals.
In fourteenth-century England, peasant girl Christine Carpenter is so attracted to a statue of the Virgin Mary that the local priest (who lusts after her) suggests she be walled up in the church as an anchoress, a holy woman with responsibility for blessing the villagers. But when the priest has Christine's mother tried as a witch, she digs herself out of her cell, a crime for which the punishment is death.
