The tangled tale of a young family's struggles with a malevolent force that affects each family member differently. Rendered through police evidence, Mark, Marcela and Mia are tormented by a primal Greek mythological demon called Mormo.
A puppy and a cat are in the movie, but you don't see either of them die. In the last half-hour there's blood that might have been either animal's, and a brief glimpse at something furry that was perhaps supposed to be a cat's corpse, but that's about it. There are also animal bones the characters see throughout the film.
