"The Last Oxygen City" Earth’s atmosphere is almost gone. Cities survive inside giant glass biodomes — until a scavenger outside discovers the domes aren't as safe as they seem.

Synopsis

In a future where Earth's atmosphere is nearly depleted, humanity's last refuge lies within massive, enclosed biodome cities. These glass cities offer a fragile sanctuary, meticulously maintained to provide breathable air. However, the illusion of safety shatters when a resourceful scavenger, surviving in the toxic wasteland outside, stumbles upon a disturbing secret: the domes are not as secure as their inhabitants believe. As the scavenger delves deeper, they uncover a hidden vulnerability that threatens the fragile ecosystems within the domes. With the lives of everyone inside hanging in the balance, the scavenger must find a way to expose the truth and fight to protect the last vestiges of civilization, even if it means risking everything they have to save the cities that once seemed impenetrable.
