A century after Earth became uninhabitable, humanity clings to survival aboard a dying space station—until 100 young prisoners are sent down to test if the planet can sustain life again. The 100 arrives expecting a barren wasteland, only to discover that nature, and something far more dangerous, has reclaimed the world below. Stripped of authority and forced to fend for themselves, these expendable delinquents must navigate a brutal landscape where their greatest enemy might be each other. Survival demands sacrifice, and every choice becomes a matter of life and death.
