The 100

Based mostly on the books by Kass Morgan, this present takes place 100 years sooner or later, when the Earth has been deserted because of radioactivity. The final surviving people dwell on an ark orbiting the planet — however the ark will not final without end. So the repressive regime picks 100 expendable juvenile delinquents to ship all the way down to Earth to see if the planet continues to be liveable.
