The people of Salem capture and execute three witches for practicing witchcraft. Before their deaths, they vow to return to Salem 300 years on Halloween to exact their revenge. Three hundred years later, a skeptical, newly transplanted Californian, Max, explores the ruins of the legendary witches house and dares the witches to manifest themselves. Disregarding the warnings of his sister and girlfriend, Max lights the Candle of Black Flame. With that, the witches reappear to wreak havoc on the town. The kids take off with the witches spellbook. The sorceresses, who will die by the morning light if they don't recite the incantation for immortality, have to get the books by whatever means they can.
