This colorful horror tale begins with Benito Freire (Jose Luis Lopez Vazquez), a pedlar and trader of charms and fabrics in a small village in northern Spain. He spends his spare time as a wolf man, murdering women and burying their corpses in the Ancines Woods. Only a forest dwelling witch knows his transformation is caused by epileptic seizures. The Abbot (Antonio Casas) is called on to form a team to investigate, and local farmers set out wolf traps in an effort to halt the harrowing murders.
