A three-mile-wide asteroid is on a collision course with Earth, and impact is only years away. This docudrama plays out the scenario as a real crisis, mixing dramatized news broadcasts and government briefings with interviews from scientists and engineers who lay out what an actual evacuation would require. The film walks through the physics of the impending strike, the shockwaves, firestorms, and climate collapse that would follow, and then turns to the logistics nobody wants to think about: who gets a seat on a spacecraft, how many people could realistically be moved off-planet, and where they would even go. Space agency plans for underground shelters and off-world colonies get weighed against the sheer scale of a species trying to save a fraction of itself. The tone stays close to a news event rather than a disaster movie, treating the science as the story rather than the spectacle. It ends less as a rescue plan than an argument about triage on a planetary scale.
