The beginning of the film resembles a traditional detective: at night on the streets of new York someone commits crimes that make the blood run cold. Innocent people are dying. The police officers were off their feet, but not a step closer to the solution. And then it becomes clear that the murders committed so mysteriously inexplicable that can not be the work of man, even the most sophisticated maniac. Then police Ralph Archie, being a deeply religious Catholic, turns to the priest Mendoza for help. He is familiar with exorcism, so he lifts the veil to the other world. It turns out that humanity is in danger. The dark forces started hunting for human souls. We must not tarry, an urgent need to destroy evil and save the human race from danger. What will the police officer do? Will he and his assistants be able to defeat the devil?
