A century after Earth was devastated by a nuclear apocalypse, 100 space station residents are sent to the planet to determine whether it's habitable.

100 years in the future, when the Earth has been abandoned due to radioactivity, the last surviving humans live on an ark orbiting the planet — but the ark won't last forever. So the repressive regime picks 100 expendable juvenile delinquents to send down to Earth to see if the planet is still habitable.

An ex-C.I.A. operative is brought back in on a very personal mission and finds himself pitted against his former pupil in a deadly game involving high-level C.I.A. officials and the Russian President-elect.
