Deliver Us from Evil (2014)

In Iraq in 2010, a four-man Marine team approaches a firefight across open desert. One Marine is shot in the head, while the others pursue hostile forces into a tree line. After injuring several hostiles with a grenade, they discover an underground stairwell. Two descend, and PFC J. Tratner activates a bodycam. At the bottom, they encounter a foul smell and an apparent room; their lights and camera suddenly fail, followed by screams.

In The Bronx in 2013, veteran NYPD Special Operations Sergeant Ralph Sarchie and his partner Butler respond to a domestic disturbance involving former Marine Jimmy Tratner, whose wife has been badly beaten. Deep scratches cover the floor, and Sarchie arrests Tratner after he flees. The officers assume he is mentally ill or intoxicated.

Sarchie and Butler later investigate a woman, Jane Crenna, who threw her toddler into the lion enclosure at the Bronx Zoo. They find her in the lemur pen, scraping the ground while reciting "Break On Through (To the Other Side)". Sarchie encounters a commercial painter inside the lion enclosure but is attacked by the lions. After Jane is transferred to a mental health facility, Jesuit priest Mendoza visits her family, who suspect something supernatural is occurring.

Responding to another disturbance, Sarchie investigates a house where lights and candles repeatedly fail. The family had employed two painters in the basement, where most disturbances occurred. Sarchie discovers one painter, David Griggs, dead and decomposing. At Griggs's apartment, they find Alphonsus Painting business cards and photographs linking Griggs to Jane and Jimmy, as well as to a third Marine, Mick Santino—the painter at the zoo.

Mendoza believes Jane is possessed, explaining that human-created secondary evil can provide demons with access to the world. Sarchie remains sceptical until he begins experiencing strange sights and sounds himself. He discovers an pictograph of an owl and a recurring combination of Latin and ancient pictographs beneath painted walls at several locations. Reviewing Tratner's military footage, he finds the same message in a cave in Diyala. Mendoza identifies it as a bridge between Christian and pagan theology that could open a door for demons, and suggests Sarchie's intuitive "radar" makes him particularly susceptible.

Sarchie, Butler and Mendoza are attacked by Santino and Tratner. Mendoza subdues Tratner with his cross, but Santino kills Butler. Mendoza tells Sarchie that he must humble himself before God and confess his sins. Sarchie admits killing a child predator named Marvin after discovering him at the scene of a child's murder, and confesses that he has since felt a growing darkness within him. Mendoza absolves him.

Sarchie's daughter later sees her stuffed owl move and encounters Santino in the hallway. Santino calls Sarchie while abducting his wife and daughter. Sarchie returns home with backup, and Santino is arrested. Mendoza and Sarchie perform an exorcism, during which Sarchie learns the demon's name, Jungler. Using the name, Mendoza frees Santino, who reveals that Sarchie's family is being held in an Alphonsus Painting van at a storage facility.

Seven months later, Sarchie attends the baptism of his second child, Daniella Anne Sarchie. He proudly renounces Satan. A closing placard states that Sarchie retired from the police force and continued working with Father Mendoza.
