Nightworld (2020)

NightWorld is a ruined dystopian city where the sun no longer shines and "Light" is strictly forbidden (other than moonlight and starlight). The students at the crumbling NightWorld Academy secretly believe in the Light Who Has a Name (their reference to Christ), and begin to revolt against the sinister Headmaster Brimstone (who also runs the town), culminating in a revolution and a final showdown between light and dark.
