Teresita, the only daughter to a wealthy couple, begins to be troubled by loud sounds and visions of a tall man in black walking towards her menacingly. Soon she becomes plagued by strange physical symptoms, visions of arms extending from the walls to grab at her...and sometimes she gets violent. A priest is called in to try and wrench the devil from her body.
