A visit to a 16th-century castle -- said to belong to the devil and containing a portrait of a woman who looks just like young Helga (Rosalba Neri) -- turns into a nightmare in this mesmerizing Italian horror classic directed by Paolo Lombardo. When Helga ends up spending the night in the ominous mansion, she dreams of a medieval past that includes rapists, brutal vampires and a mysterious hooded executioner.
