Emily De Blancheville returns to her ancestral home to find that her father has been transformed into a disfigured monster. The hideous beast, driven insane by an ancient family curse, is determined to kill his daughter before she turns twenty-one. With her birthday approaching, the creature escapes from his tower lair, intent on a deadly attack. Helplessly trapped in the manor, Emily appears doomed to a gruesome end when she falls into a mysterious trance.
The Blancheville Monster (A.K.A. Horror) was loosely adapted from Edgar Allan Poe's Fall of the House of Usher.
