In 1660s Scotland, an infamous Witch Pricker is brought to Auldern by the town’s magistrate to garner confessions of witchcraft from three women. It quickly becomes clear, however, that the motivations for killing these women is not justice or fear of witchcraft, but a personal vendetta and power grab. When one of the women discovers that the Witch Pricker is actually another woman in disguise, the Witch Pricker has to decide what justice really looks like when her own safety is at stake. Will she kill an innocent woman to save her own?
