The 100

Watch The 100 this spring!

For three seasons, the 100 have fought to survive. The fight has torn them apart, turned them against each other and taken the lives of their closest friends. In season three, our heroes found themselves at the epicenters of both the Grounder world and the struggle for Arkadia's soul. Despite their best efforts, all out war appeared unavoidable until a new, even more dangerous threat  exploded to the surface, ALIE. Now, in the wake of the epic season 3 finale, a hard truth lands on the shoulders of those who remain. What's left to fight for now? Will they go quietly into the night, or will they find hope and faith in each other, as they face their darkest chapter yet? (Credit: cwtvlink.com)
