Orphaned twins Frieda and Mariah are en route to their uncle Gustav Weil's homestead. What they don't know of their uncle Gustav is that he is the head of "The Brotherhood," a vigilante group of witch burners, scouring evil from the surrounding lands.
Once they arrive, they are subjected to Uncle Gustav's tyrannical rule, which leads to Frieda's late night scheming in order to rid herself of her oppressive uncle. When they sneak out to out to visit Count Karnstein we learn that Frieda has an evil side, while the other sister remains pure. Soon Uncle Gustav's band of (not so) merry men learn of Frieda's wicked ways and rally to lay siege to the evil Count's castle. Huzzah!
Do you love busty women in period corsets? Then you're in the right place! Here we are with yet another Hammer Studios period flick dripping with atmosphere and cleavage. And really, there's nothing wrong with that. This time around we get a Hammer vamp story with a twist. With a heavy dose of Salem Witch Trial style zealotry, we have a vampire film with two antagonists instead of one. Also giving this foray into fangs a new spin is Hammer's departure from their standard vampire canon and giving us a new origin line to vampirism with a heaping helping of Satan!
Peter Cushing stars as Uncle Gustav, the overzealous leader of The Brotherhood. With typical Cushing flair we are given a religious man off the deep end in his faith and devotion. He is leading the charge to put the torch to many a hapless maiden suspected of evil with no real evidence to back it up and we see many a woman put to death for dubious reasons.
With drained corpses starting to show up about town, The Brotherhood knows no other way to fight this new evil and turns to the random accusations of single women living alone. If they're not married, they have to be evil right? Cushing pulls off the Uncle Gustav role with his usual flair and mastery and presents us a man believing fully in his holy mission despite the cost to loved ones and innocents.
Playing the fanged bad boy this time around is Damien Thomas. In a slightly over the top performance as the evil Count Karnstein, Thomas gives us a man seeming slightly surprised by his new found fangs, but as he sure loves Satan he's going to run with it. Looking much like Saturday Night Live’s Jimmy Fallon in a wig and fancy pants, the Count is shown to us as a man that is evil mostly because he is a noble and rather bored with life. Holding random Satanic rituals as dinner entertainment in his homestead on a regular basis, Karnstein appears to be slightly surprised by the gift from his dark lord.
