A teenage girl and her mom think Crestwick will be a great place for them to have a new beginning but little do they know, the house they are moving into has been plagued by an evil demon known as Nefas dating back into the 1800's. Nefas has fed on the souls of innocent young girls and now has a new target. In order to save this teenage girl and her mother, a skeptical, small town doctor is forced to confront his own demons before another girl suffers a gruesome fate in his family's old house.

ILLAKSI valitsemani elokuva, A Demon Within, oli olevinaan jonkin sortin kauhuleffa mutta eipä onnistunut olemaan jännittävä. Tylsyyteen vajoaminen oli melkoisen lähellä ennenkuin leffa jossa ei tuntunut taphtuvan mitään, loppui. ■
