In a near-future world reeling from climate disasters, a defunded space agency is pulled back into action when astronomers detect a rogue asteroid that has altered its course — and is now heading directly toward Earth. As nations argue and panic spreads, a disillusioned former astronaut and a rebellious teenage tech prodigy must unite with a privatized space conglomerate to launch a last-ditch mission. But as the team races against time, they uncover that the asteroid might not be a natural object — and stopping it could trigger something far worse.
