Summary

A young couple, George and Kathy Lutz, move into a beautiful Long Island home with their three children, only to discover the house was the site of a horrific mass murder a year earlier. As they settle in, a series of increasingly disturbing supernatural events tests their sanity and threatens their family, while a local priest attempts to bless the house and confront the malevolent presence within.
