About 12 Monkeys
12 Monkeys is a time-travel thriller that reimagines Terry Gilliam's 1995 film as a serialized mystery. In a devastated 2043, a deadly plague engineered by a shadowy cabal known as the Army of the 12 Monkeys has wiped out most of humanity. Scavenger James Cole is recruited by a small band of survivors who have built a crude time machine, and he is sent into the past with a single mission: find the source of the virus and erase it from history before it can ever be released.
In 2015, Cole tracks down virologist Dr. Cassandra Railly, a respected scientist whose name was the only clue he carried back through time. Their reluctant partnership grows into the emotional core of the series as they chase a moving target across years and decades, uncovering a conspiracy that reaches far deeper than a single pathogen. Along the way they cross paths with Jennifer Goines, the brilliant and unstable daughter of a pharmaceutical mogul, whose fractured mind hides crucial secrets about the coming apocalypse.
As the seasons progress, the show expands from a race to stop a plague into a sprawling saga about fate, free will, and the cost of rewriting time. The Army of the 12 Monkeys is revealed to be pursuing something far stranger than mass death, and Cole, Cassie, and Jennifer must confront paradoxes, doomed loops, and impossible choices. Praised for its intricate, tightly plotted timeline and satisfying payoffs, 12 Monkeys built a devoted fan base across its four seasons before concluding on its own terms in 2018.
