But the grieving couple unknowingly becomes the prey of a family of vengeful spirits that resides in their new home, and before long they discover that the seemingly peaceful town they've moved into is hiding a terrifyingly dark secret. Now they must find a way to overcome their sorrow and fight back against both the living and dead as the malicious ghosts threaten to pull their souls - and the soul of their lost son - into hell with them.
