Five years after his infant son is murdered in a horrific, senseless massacre, police detective Emmanuel Ritter (Joaquín Cosio) is drawn into the mystery of another mass killing that eerily parallels the first. Begrudgingly teaming up with an American priest who’s become a paranormal investigator (Tate Ellington), Ritter follows the trail of an increasingly disturbing series of clues that point to the involvement of an elusive, excommunicated man of the cloth with satanic affiliations (Tobin Bell). This high-stakes procedural drama rapidly evolves into a vividly original outing in the subgenre of exorcism horror and a potent political allegory.
