Professor Norman Taylor teaches at Hempnell Medical College. He's quite good and has earned the respect of his colleagues. Some of the wives don't quite feel the same about his wife Tansy however. Norman is quite shocked to learn that Tansy has been practicing witchcraft since he'd had an accident two years before in Jamaica. Tansy is convinced that it's her witchcraft that saved him. He thinks it's all nonsense and destroys all of her paraphernalia, including a small photo of himself Tansy kept in a locket. Soon after, Norman's world begins to fall apart. One of his students accuses him of molesting her and as a result another student threatens him with a gun. When evil spirits try to take him, Tansy decides that she will die in his place. He races to save her but Tansy isn't isn't the only practitioner of witchcraft.

Movie Trivia:
Peter Wyngarde was only cast because the original actor became ill.
When Norman hides in the classroom "I Do Not Believe" is written on the chalk board with other key words related to witchcraft. Something off screen appears to him and he backs up to the chalkboard in fear. After the PA system is silenced, he walks back to the door. The blackboard has been smudged, creatively revealing the phrase "I Do...Believe"
The shot of the eagle bursting through the door was achieved by punching a glove puppet through a miniature of the door. There are only a few frames of this sequence before a very quick cut to a shot of an actual eagle in a miniature of the hallway, but the shape of a hand and wrist can just be made out in silhouette.
