A man from the post-apocalyptic future, Cole uses a dangerous, untested method of time travel to get from 2043 to the present day. He is on a mission to locate and rid the world of the source of the plague that will eventually annihilate the human race. Assisting him is Dr. Cassandra Railly, a virologist who must decide whether to do harm in order to save the world -- regardless of the fact that she has taken the Hippocratic oath. The sci-fi series is based on Terry Gilliam's 1995 film, which starred Bruce Willis as Cole.

Critics Consensus

12 Monkeys continues to raise the bar with each marvelously complex episode in a knock-out fourth season that proves as unpredictable as it is gratifying.

12 Monkeys is a sweet ride with plenty of moments to reward continued attention.

12 Monkeys has a surprising amount of thematic depth for a show that sets a climactic battle in its finale to the strains of "Time of My Life" (you know, from Dirty Dancing).

This show is a LOT, and you need to pay attention, but if you enjoy sci-fi, you'll love that there are four seasons of it to ponder the "Twelve Monkeys Theory".

12 Monkeys takes the good stuff from the movie...and builds upon it, creating a driving narrative that only occasionally confuses -- in the best way possible -- when skipping back and forth in time.

Season 4 is, hands down, the best season of the show and every episode tops the last. There's no way I could have predicted 95% of what's happened this season and yet everything feels organic.

Forgot how this series was bonkers and awesome at the same time.

It's a fun action sci-fi with a cast that feels like family by the end, which is something to love in its own right! And 100% best series finale ever.

I didn't like the ending because everyone remembers so time resetting doesn't apply apart from that show was very good except s3 which was at its lowest level.

Just binged all four seasons. Consistent and enjoyable throughout

I didn’t think they would be able to stick the landing and it would crash at the end but it was actually a great watch with a satisfying end.

I loved this show! It is a completely different story than the movie, which was a huge plus for me. I haven't seen better writing since this series. I'm always on the lookout for more content by Terry Matalas and Travis Fickett. This is a must-see for anyone who even remotely likes sci-fi! Watch it, I know you'll love it. See you soon
