A family inherits a spectacular old house from an eccentric uncle (Academy Award Winner F. Murray Abraham). But the house seems to have a dangerous agenda all of its own. Trapped inside by shifting walls, a father and daughter (Tony Shalhoub and Shannon Elizabeth) encounter powerful and vengeful ghosts that threaten to destroy anyone in their path. The family is joined by an offbeat ghost hunter who is determined to free the spirits imprisoned in the house. Caught in a frantic race to save themselves before it is too late, the human inhabitants realize the house is a riddle which contains the key to their imminent salvation...or destruction.
