Based on the series of books by Hugh Howey. In the near future, the surviving 10 thousand people live in a huge bunker that is 144 floors deep. People believe that the world is dead, the air outside is poisoned, and going to the surface is deadly dangerous. They receive all the information through huge screens, on which images from external cameras are broadcasted. Day after day, looking at the lifeless grey landscape, the inhabitants obediently follow the established rules, the most important of which is never to leave the bunker. The second season of Silo Project continues the story.
