The Haunting in Connecticut

When their son Matt (Kyle Gallner) receives a diagnosis of cancer, Sara (Virginia Madsen) and Peter (Martin Donovan) Campbell move to Connecticut to be closer to his doctors. At first all is well, but then Matt becomes increasingly disturbed by what appears to be paranormal activity. Sara turns to a priest for help, and the ghosts are seemingly banished -- but Matt's condition takes a sudden and unexplained turn for the worse, and the lives of Sara and the rest of her family are endangered.
