When Catherine Porter murders her only son and takes her own life, no one can understand why. Vilified for her crimes, she becomes synonymous with everything evil and wicked amongst the locals, and parents begin using her name to scare their errant children into behaving.

Soon after her death, reports begin to circulate that her ghost has been seen inside her old house. Over the years, the sightings continue, sending most of the house’s occupants running from the property, screaming into the night, never to return.

When the Jefferson family moves in, they decide to hold a séance to finally rid the property of its unwanted guest. But in doing so, they unleash something even more terrifying: a malevolent force that will stop at nothing to take back its domain.
