In the thirteenth century, the region around the city of Berzano was ruled by a legion of Templar Knights, who sought eternal life through the ingestion of human blood. They terrorized the region by harvesting the land and committing human sacrifices. They eventually got imprisoned and executed, left hung out for the crows to peck out their eyes. In modern day Portugal, a group of people visits the abandoned city, which awakens the Templar’s corpses, terrorizing the region again.

The legendary Loreley has been living for centuries in a grotto beneath the river Rhein in Germany. Every night when the moon is full, she turns into a reptile-like creature craving for human blood. When one girl after another of a nearby boarding school is killed by her, a hunter named Sirgurd is engaged to kill the monster.
