Cole (Bruce Willis) is sent back in time to save the human race from a deadly virus that has forced mankind into dank underground communities in the future. Along his travels he encounters a psychiatrist (Madeleine Stowe) and a mental patient, brilliantly portrayed by Brad Pitt, who may hold the key to a mysterious rogue group, the Army of the 12 Monkeys, thought to be responsible for unleashing the killer disease. Believing he can obtain a pure virus sample in order to find a cure in the future, he is met with one riddle after another that puts him in a race with time. This sci-fi masterpiece from the genius mind of Terry Gilliam is a modern-day classic.
