The story of a family struggling to survive in a world terrorized by a deadly primeval species that has evolved for millions of years in the pitch-darkness of a vast underground cave system, hunting only with their acute hearing ability. As the family seeks refuge in a remote haven where they can wait out the invasion, they start to wonder what kind of world will remain when they're ready to emerge.
