The 100 - S04 (2017)

The fight to survive has torn The 100 apart, turned them against each other, and taken the lives of their closest friends. Last season, our heroes found themselves at the epicenter of both the Grounder world and the struggle for Arkadia’s soul. Despite their best efforts, war appeared unavoidable, until a new, even more dangerous threat – one that had been quietly rising all along – exploded to the surface: ALIE, the A.I. that ended the world, offered relief from pain and eternal life in the “City of Light.” But as her ranks grew, it quickly became clear that she was building an army dedicated to controlling all sentient life on Earth. This was no longer a battle between warring factions; it was a fight for humanity itself. Now, a hard truth lands on the shoulders of those who remain. Will they go quietly into the night, or will they find hope and faith in each other, as they face their darkest chapter yet?
