Output: Peter and Bronny Taylor go on a vacation to the Grand Canyon in Arizona with Stephanie, their teenage daughter, and Mikey, their adolescent autistic son. Mikey discovers a small Kiva cavern, where he finds black rocks with symbols on them. He takes the rocks, keeping a secret untold. When the Taylors return home, strange things begin to happen. Bronny finds that the kitchen taps keep turning on, and Stephanie sees handprints on a steamy mirror, both of which Mikey blames on “Jenny”. After Stephanie gets home from school, she vomits into a container and puts it under her bed. Bronny catches her, and she and Peter learn that Stephanie has been throwing up for a while; there are many such containers under her bed. They take Stephanie to a hospital for help, leaving Mikey at Bronnys mothers house. Bronnys mother finds Mikey trying to kill her cat, much to Peter’s disbelief. At home, Bronny searches online for answers to the strange activity and learns about the Anasazi Indians, who have believed that demons were bound to rocks hidden in underground caves. If the rocks are taken, the demons take the shape of a crow, snake, coyote, wolf, and buffalo. The family has already had encounters with a crow and a snake. The demons connect to young children who are dragged into their world, triggering an event known as The Darkness. The only way they can be banished is if the rocks are returned to where they were found by someone who is not afraid. Bronny finds a wall on fire in Mikeys room, but Peter rules out the possibility of ghosts. They later find Mikey covered in black marks from the fire, with blood pouring from his mouth. Later that night, Bronny has a nightmare of a wolf. Depressed, she starts drinking. In Mikeys room, the firedamaged part of the wall is revealed to be a portal. Stephanie begins being choked by handprints appearing all over her wall and body. In the tree house, Peter sees a coyote, and then sees the shadow of a demon in Stephanies window. The force stops choking Stephanie as Peter rushes in. Peter then breaks down Mikeys bathroom door, and finds him with marks all over the walls and ceiling. Peter calls a number given to him by his boss. It is a woman named Teresa, who is said to perform spiritual healings. Teresa comes over with her granddaughter named Gloria, who acts as a translator. As they cleanse the house, Teresa and Gloria go into Mikeys room, and note that this is where the real evil lives. They recite a chant as Mikey tries to enter the portal. When they realize Mikeys gone, the family races upstairs. Peter sees Mikey walking into the portal with the demons. He finds the stones and follows Mikey into the portal, but cant set the stones down due to his fear. He offers to swap places with Mikey but Mikey ends the event of The Darkness by picking the stones up and putting them back down, saying that he is not afraid. The demons have been completely banished, and Peter and Mikey jump out of the portal together. It disappears, and Gloria declares that the house is clean of evil energy as Peter and his family reunite together.
