When 9 (Elijah Wood) springs to life, it finds itself in a post-apocalyptic world where humans no longer exist, and the only signs of life are sentient rag dolls like itself and the machines that hunt them. Though it is the youngest of the group, 9 convinces comrades that the only way to survive against the machines is to stop hiding, go on the offensive, and find out why the machines want to destroy them. As 9 and the group learn, civilization hinges on their success or failure.
