The 100

The 100

The fight to survive has torn them apart, turned them against each other, and taken the lives of their closest friends. Last season, a new, even more dangerous threat arose: the A.I. that ended the world was building an army dedicated to controlling all sentient life on Earth. No longer a battle between warring factions; it was a fight for humanity itself. The 100 face their darkest chapter yet.
