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 30, 2026 Season 4 of The 100 is severely underrated, and I thought there was brilliant writing in this season. Everyone is under the same threat, and that threat is Praimfaya. The world is ending, and every single person who was once an enemy had to work together to save the human race from extinction. There were so many great things about this season, which included the level of emotion, how high the stakes were, the character arcs, and even the deaths hit so hard. Skaikru was grasping at so many ways to save the human race. Still, it all came down to Thelonious finding a secret bunker that became the main fight of this season. Everyone was deciding who would get the bunker, so there was a massive fight to determine who would occupy it. Octavia decided on how the spots were going to be filled within the bunker, and the other main stars of the show found themselves in different spots at the end of the season. Overall, the season ended perfectly, and I can't wait to watch Season 5 again.

It starts off slow and really builds up to a dramatic, intense finish. The character arcs this season are truly phenomenal. This season proves that the show is at its strongest when the characters are the primary focus. It is also centered around the main theme of the show: what it takes to survive. Episodes 10 and 13 are particular standouts. See more Josh W @RT85185052 Jan 2, 2025 The show finally returns to its glory after the somewhat let down of season 3. Thoroughly enjoyed the whole season. See more Pedro Henrique C @Pedro2005 Jan 31, 2024 Perfect, I really loved this season, starting next season See more DYLANZS W @RT72238365 May 1, 2023 The whole feel to this season was just great I really love how it all blends together See more Read all reviews
