Howling V: The Rebirth

A group of people is invited by a Count to a castle in Budapest, where centuries ago a family living in that same castle was slaughtered by a couple who later committed suicide and only a baby survived. Upon their arrival, the group comes to know the story of the region which, 1,000 years before, was being terrorized by packs of wolves, supposedly being controlled by Satan himself, disguised as a man at day and as a wolf at night.
