Martha Peters and Mary Davis noticed that women weren’t making many horror movies in the 1960s, so they wrote this, which would be directed by Tom Moore, who  produced Horror High, The Town That Dreaded Sundown, The Norseman and directed, wrote and produced Return to Boggy Creek.

As for Peters and Davis, only Davis would work on another film, writing the script for S.F. Brownrigg’s Scum of the Earth.

This starts like Black Sunday, as a witch (Marie Santell) is being put to death after having been betrayed by her coven. As they take her to the gallows, she says that she will come back for revenge on the family of MacIntyre Stuart (Robert Elston), who is why she has been charged.

Three hundred years later, Professor Mac Stuart (Elston) is dumb enough to have a party and invite his swinging hippy students over to his place, where Jill (Anitra Walsh) steals one of Mac’s books, the Red Book of Appin, and soon becomes possessed by the witch after she, Sharon (Barbara Brownell) and Harry (Jack Gardner) — her boyfriend Alan (Darryl Wells) doesn’t want to play with evil — conjure up the evil woman, who ends up killing all of her friends to become the ruler of our world.

Pretty simple, but also pretty awesome, as 1972 was a way groovier place than 2024. The strangest thing is that instead of, you know, just killing Mac, the possessed Jill asks him all about telephones and coffee while a Moog synth soundtrack dibble dabbles. Man, could we all just live in this?
