The 100: Day 21

Overview: In the future, humans live in citylike spaceships orbiting far above Earth's toxic atmosphere. No one knows when, or even if, the long-abandoned planet will be habitable again. But faced with dwindling resources and a growing populace, government leaders know they must reclaim their homeland...before it's too late. Now, one hundred juvenile delinquents are being sent on a high-stakes mission to recolonize Earth. After a brutal crash landing, the teens arrive on a savagely beautiful planet they've only seen from space. Confronting the dangers of this rugged new world, they struggle to form a tentative community. But they're haunted by their past and uncertain about the future. To survive, they must learn to trust-and even love-again.
