A cop and a priest team up on a case of demonic possession in this horror film based on actual cases investigated by retired NYPD police officer-turned-demonologist.

When a frightening wave of violence sweeps through New York City, troubled cop Sarchie fails to find a rational explanation for the bizarre crimes.

His eyes are opened to a frightening alternate reality, however, when a renegade Jesuit priest convinces him that demonic possession may be to blame for the gruesome murders.

Together, this unlikely duo wage a valiant supernatural struggle to rid the city of an otherworldly evil. But the closer they get to the source of this malevolent scourge, the more immediate the danger becomes to Sarchie, his pregnant wife Jen and their young daughter Christina.
