This story is very much in the vein of the American "Omen" franchise. A little girl with powers to get her way and no morals to constrain how far she will go to get it. He mother is weak and afraid of her child. Through a crazy chain of event a psyche patient wands up staying their home and of course no one believes her tales of the strange child.

Horror at its finest, and i wish someone would do an updated version with today's effects, lighting and CGI. It's old school creepy. Also if someone tells you that that cute girl next door killed her soon to be sister in law ...you might not want to dismiss the notion right away. : )
