Synopsis

The lives of the Barretts, a suburban New England family, are torn apart when fourteen-year-old Marjorie begins to display signs of acute schizophrenia. To her parents' despair, the doctors are unable to halt Marjorie's descent into madness.

As their stable home devolves into a house of horrors, they reluctantly turn to a local Catholic priest for help, and soon find themselves the unwitting stars of The Possession, a hit reality television show.
