David Brault, a 23-year-old college student who goes by "Gone," has moved into the abandoned Damen Silos on the Chicago River, treating the derelict grain complex as a testing ground for life after collapse. The film follows him inside the structure, hauling water, scavenging materials, and laying out the skills he says anyone would need if the systems around them stopped working: shelter, food, defense, routine. He talks through his reasoning to the camera, framing the silos less as a stunt location than as a classroom for a scenario he takes seriously. Other people drawn into his orbit appear too, giving some sense of how his choice reads to those who did not make it. The film stays close to Brault's own voice and daily tasks rather than bringing in outside experts, so the case for his lifestyle rests on watching him do the work himself, day after day, inside a building most people only see from a bridge.
