SAW veterans James Wan and Leigh Whannell team with PARANORMAL writer/director Oren Peli to give the familiar haunted house story an exciting new twist with this tale of a family that moves into an old house and begins to suspect they are under siege from otherworldly forces when their young son inexplicably falls into a deep coma. As devoted parents Josh (Patrick Wilson) and Renai (Rose Byrne) struggle in vain to uncover the root cause of their son's condition, the stress of the situation gradually begins to take its toll on their once-strong relationship. Later, when darkness falls and specters appear to reach out for them from the shadows, the frightened parents realize they're dealing with powers beyond human comprehension. Barbara Hershey and Lin Shaye co-star.
