12 Monkeys

Cole (Brue Willis) is sent back in time to save the human race from a deadly virus. Along his travels, he encounters a psychiatrist (Madeleine Stow) and a mental patient, brilliantly portrayed by Brad Pitt, who may hold the key to the mysterious 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 for time. (official distributor synopsis)
