In the tradition of such real-life horror movies as The Exorcist and The Exorcism of Emily Rose, The Haunting In Connecticut tells the astounding true story of one family's supernatural ordeal.
When Sara (Virginia Madsen) and Peter (Martin Donovan) Campbell's son Matt (Kyle Gallner) is diagnosed with cancer, they uproot their family to Connecticut for his treatment. As the family settles into their new home, Matt grows increasingly disturbed by paranormal activity that seems to inhabit and possess the house. They soon learn that their charming Victorian home has a disturbing history: not only was the house a transformed funeral parlor where inconceivable acts occurred, but the owner's clairvoyant son Jonah served as a demonic messenger, providing a gateway for spiritual entities to crossover.
Now unspeakable terror awaits, when Jonah, the boy who communicated with the dead, returns to unleash a new kind of horror on the innocent and unsuspecting family.
