Sir Richard Fordyke (John Turner) returns to his father's estate with his new bride Elizabeth (Heather Sears) to find things are not right. A young girl has been killed and her last words were Richard's name. The tenants are becoming rebellious, especially as Richard has apparently been seen on horseback being chased by his dead ex-wife!
Mysterious happenings at night further raise the tensions. Suspicion falls on Sir Richard although he maintains he was in London wooing Elizabeth. Richard begins to question his own sanity as his assistant Seymour (Peter Arne) or her father's carer Diane (Ann Lynn) wonder if there is something Devilish going on.
An intelligent psychological horror, you might guess what is really going on before too long and before Richard who is a little too overwrought, but this is a very well structured and made film.
