When, at the beginning of Deus Irae, Father Javier stares at a crucifix, his expressions and his hands suggest that the nerves are consuming him. A flashback reveals that this priest devotes his life to visiting families that claim to have seen things that do not belong to this world and cleansing their homes from the demons that try to possess them. But, upon returning to those houses, he notices that the evidence is always destroyed. This way, he discovers that a clan is after him, and must decide whether to hide from them or join them. In times when horror cinema tends to fall into the hands of directors that seek to build narratives that are introspective and close to reality, Pedro Cristiani goes back to old-school horror, where gore and the physical experience are above any other kind of feeling. A cinema that places the camera in front of the faces of the bloodiest demons and, instead of giving logic to them, chooses to face them whatever the cost.
