A young coed (Nan Barlow) uses her winter vacation to research a paper on witchcraft in New England. Her professor (Christopher Lee) recommends that she spend her time in a small village called Whitewood just north from the school. He also recommends she stay at the "Raven's Inn," run by a Mrs. Newlis. She gets to the village and notices some weird happenings, but things begin to happen in earnest when she finds herself "marked" for sacrifice by the undead coven of witches. It seems that the innkeeper is actually the undead spirit of Elizabeth Selwyn, and the "guests" at the inn are the other witches who have come to celebrate the sacrifice on Candalmas Eve. REDUCED 7/12.
