When nuclear Armageddon destroys civilization on Earth, the only survivors are those on the 12 international space stations in orbit at the time. Three generations later, the 4,000 survivors living on a space ark of linked stations see their resources dwindle and face draconian measures established to ensure humanity's future. Desperately looking for a solution, the ark's leaders send 100 juvenile prisoners back to the planet to test its habitability. Having always lived in space, the exiles find the planet fascinating and terrifying, but with the fate of the human race in their hands, they must forge a path into the unknown.

Rowan C @RowanC3 Jun 20, 2026 Season 3 of The 100 was really good, but I don't think it's better than Season 2. This season really digs deep into the City of Light storyline, and the conflict between the Grounders grew even stronger. Allie was the main person behind the City of Light, and she was mainly trying to save humanity from another world-ending event. She was forcing people to take it, which created a huge problem that even stretched to the Grounders taking it. She controlled everyone and wanted to control everything, so she had to be stopped. A new chancellor stepped up at Arcadia, and he hated Grounders with a passion. Charles Pike even went as far as to slaughter a whole camp that was there to assist them, and he was soon brought to justice by Octavia Blake (Marie Avgeropoulo). People were lost, but the most important information was that Clarke learned crucial news that will play a huge part in Season 4. Overall, Season 3 had very high stakes and a lot of moments where I was on the edge of my seat. See more Gavin P @gavaperk22 Feb 25, 2026 An incredible season with interesting character arcs and phenomenal world-building. Despite cramming lots of plot and storylines into a singular season (which is admittedly this season's main downfall), the story comes together quite nicely in the end. This season really is a turning point for the series and sets up the rest of the seasons in a nice way. See more Josh W @RT85185052 Jan 2, 2025 The third season is my least favorite but thats not to say its bad. The plot is not terrible I just don"t believe it was executed to its full potential. Bellamy gang rise up. See more Pedro Henrique C @Pedro2005 Jan 1, 2024 Not as good as the last two seasons See more Anthony T @tomscove Jun 4, 2023 Killing Lexa killed this show for me.
