The kids are trapped in a pocket dimension by a demon who can control time and space. It torments them, mostly emotionally, just for fun. Think the way you play with a pet mouse or hamster, putting your hand in its way so I has to go around you, or picking it up and putting it back where it started when It's trying to get somewhere. Or better yet, playing The Sims. The demon removes doors from where they were, trapping the kids in rooms, removes their toilet, sticks their toys on the ceiling where they can't reach them. Creates copies of their parents to torture them with. Ending shows the demon torments the kids for years at a time and has done it to a countless number of kids over eternity.
