In 1989, emergency responders received a 9-1-1 call from
Maria Rossi (Suzan Crowley) confessing that she had brutally killed three
people. 20 years later, her daughter Isabella (Fernanda Andrade) seeks to
understand the truth about what happened that night. She travels to the
Centrino Hospital for the Criminally Insane in Italy where her mother has been
locked away to determine if her mother is mentally ill or demonically
possessed. When she recruits two young exorcists (Simon Quarterman and Evan
Helmuth) to cure her mom using unconventional methods combining both science and
religion, they come face-to-face with pure evil in the form of four powerful
demons possessing Maria.
Many have been possessed by one; only one has been
possessed by many.
