Wicked Stepmother

“Which Witch is which?”

Jenny Fisher (Colleen Camp) wants her family to get through a new arrival at the house, a stepmother named Priscilla (Barbara Carrera) who turns out to be a witch. Larry Cohen sets her loose in the Fisher home, and her spells start wrecking the household. Standing against her are the matriarch Miranda Pierpoint (Bette Davis) and a private detective, and the film treats an old family's defense against magic as worth putting on a stage.
