In this season 2, we find Clarke and his friends locked inside Mount Weather, an underground city immune to nuclear radiation where no one is safe – let alone The 100. Clarke's escape triggers a series of events for our heroes and the adults left on the ground, but also for the Natives. Alliances will be made and friendships broken, for justice to be done. In the fight for their survival, our heroes will have to ask themselves a decisive question: how far would you go to save those you love? Many will fight, some will die, and nothing will ever be the same after these 16 epic and heartbreaking episodes.
