The mansion is possessed by an evil personality with a diabolical history. A child's ghost passes through Nell. Other young specters meander through curtains, bed sheets and inhabit carved busts. The shapely Theo appears in a negligee. A man is dragged into a pond and nearly drowned by a statue.
Poltergeists slowly dismantle a towering spiral staircase as a person tries to climb it.
A man is dragged into an idle fireplace before being beheaded by a ferocious pendulum. Nell is pinned to her bed by talon-like bedposts. A piano string snaps mysteriously, nearly putting out a woman's eye. Nell has a grisly vision of a woman hanging from the rafters with a noose around her neck. Also, exploding windows, ominous shadows, bloody footprints, human bones in the fireplace, tales of tragic deaths and other assorted frights give the film a high creepiness quotient.
