In the 17th century Livonian village of Zaube, there’s something in the air, something potentially sinister and ripe with nightmarish ramifications. Several of the village’s residents can feel it: from the burly pastor’s scared, young errand boy to the local tavern’s maid. The danger manifests itself loud and clear when the pastor accuses the maid of witchcraft, leading to a trial during which an elder man proclaims himself to be a werewolf — not the traditional Lon Chaney, Jr. kind of werewolf but, rather, one rooted in Latvian folklore and hewing closer to a mad shaman. How all this tension comes to a head will change the village and its surviving inhabitants forever.
