Three hundred years ago the citizens of Devonsville accused three women of witchcraft and killed them using pretty crude (but at least in one case kind of effective) special effects. In the present day (or the early 80's at least), Suzanna Love (the film's co-writer and wife of director Ulli Lommel) comes to Devonsville to be the new school teacher.
Things don't go too well. She pretty early on tells the kids that God could be a woman, which doesn't go over too well with many of the rural folk. Paul Willson (from "Cheers"!) develops an unrequited crush on her ... and so on. Wilson and other local troublemakers decide that Love and two other young women who are new to town (a radio DJ and an environmental scientist) are reincarnations of the witches and decide to kill them.
It's hard to know what to say about this film. In fairly objective terms, it's real junk. But the ways in which it's junky start to work in it's favour. It's shot in rural Wisconsin under circumstances that are so low tech it ends up looking a bit like a home movie. Robert Walker Jr. Is on hand as one of the nice guys in town, but his presence barely registers. Donald Pleasance has a much bigger role as the town doctor, but he seems to have been available for one day. All of his scenes are shot in the same cramped edge of the same room.
The film kind of gestures at feminist themes (string independent young women persecuted by closed minded men), but kind of undoes that in a climax that suggests that they were right. Basically, I think it's an oddly watchable film that has no right to be.
Willson's head melts like that creepy Nazi in "Raiders of the Lost Ark" during the climax and that's basically worth the price of admission.
