Young college student Nan Barlow (Venetia Stevenson) arrives in the sleepy Massachusetts town of Whitewood to research witchcraft. Nan's stay at the eerie Raven's Inn takes a portentous turn when she learns its proprietor Mrs. Newless (Patricia Jessel) is the reincarnation of a witch burned at the stake in 1692. The discovery unravels the startling truth about the town: that it is really a coven of witches who have a sinister plan to sacrifice humans so that they can become immortal.
