The protagonist of this horror movie is a girl named Ada, who lives with her parents and brother in the depths of the North American forests along with other residents of the settlement. They are all members of a special sect worshiping an unknown being called Yama. It lives at the bottom of a great failure in the earth, and none of the inhabitants of the settlement has ever seen it. This deity, according to people, helps them, including cures for various diseases. And so that the creature does not turn its back on people, they offer him sacrifices ... human. Several people from the village have some kind of telepathic connection with the Pit, among them Ada and a local potter named Dowey. For his work, he takes clay from the very pit, and receives visions, images of those people whom the community should sacrifice next time. Pregnant from her own brother Ada, she finds out that the next victim that Yama will be presented with should be her.
