Subterra

In the underground city of Subterra, sealed for two hundred years after a nuclear war, a rigid feudal system divides its residents into Uppers, Mid-Tiers, and Bottom Dwellers. While the Uppers maintain control and refuse to open the dome, claiming external dangers, the Bottom Dwellers yearn for change. A diverse group of Synthetics, robots, and humans has come together with a daring plan to challenge the status quo and unlock the secrets beyond their confines.
