A married couple loses their children while on a family trip near some caves in Tijuana. The kids eventually reappear without explanation, but it becomes clear that they are not who they used to be, that something terrifying has changed them.
Review from the comment
This is a pretty straight forward film with no real surprises. Basically, a family goes to a a mountainous region in Mexico for some family time. Eventually the children of the family become lost for a night. The police find the kids and return them the next day. The parents are overjoyed, but soon realize that their pride and joy are not what they seem.
Here Comes the Devil is not a good film. Nor will it appeal to many film-goers. There is a lot of sex and nudity, implied pedophilia and even incest. These themes seem to come at times that may not even make a lot of sense. It's a quick watch, but not worth the payoff.
