Blood Creek

In 1936, a German professor, Richard Wirth, is hosted by the Wollners, a family of German emigrants in West Virginia. The Wollners believe him to be a visiting scholar, but Wirth turns out to be a Nazi occultist who seeks a Viking runestone buried on their property. When Wirth reveals he wants to use it for evil, he is interrupted by the family, who trap him in their basement and bind him through a ritual that requires frequent human sacrifices. Linked to Wirth, the family survive through the decades, operating as both captors and servants to Wirth, who they keep weakened.
