9 is a sentient rag doll who appears to be the last of his kind, living in the ruins of a decaying, post-apocalyptic Earth. He is first seen making simple constructs out of detritus – a swinging armature of scrap metal, an upright book with string tied around it, and a dummy rag doll full of tar, though the purpose behind these things is unclear at first. Hunting 9 relentlessly is the Cat Beast, a mechanical monster wearing a cat's skull for a head. It appears to be guided by a small glowing talisman which it holds in its claws. Sitting quietly, 9 stares into the mirrored surface of his own strange talisman and has a flashback.

Himiko has also been memory-wiped, possibly by the same company that produced Pinocchio, but she is fully functional. Himiko spends her days drawing maps of the city, to aid other memory-wiped people.

In the late 21st century, global warming has flooded coastlines, drastically reducing the human population. There is a new class of robots called Mecha, advanced humanoids capable of emulating thoughts and emotions. David (Haley Joel Osment), a prototype model created by Cybertronics of New Jersey, is designed to resemble a human child and to display love for its human owners. They test their creation with one of their employees, Henry Swinton (Sam Robards), and his wife Monica (Frances O'Connor). The Swintons' son, Martin (Jake Thomas), was placed in suspended animation until a cure can be found for his rare disease which is caused by the Sinclair virus. Initially frightened of David, Monica eventually warms enough to him to activate his imprinting protocol, which irreversibly causes David to have an enduring childlike love for her. He is also befriended by Teddy (Jack Angel), a robotic teddy bear, who takes it upon himself to care for David's well-being.
In the year 2073 Nicholas Sinclair is a scientist on a time travel project. An accident introduces a deadly virus in to the past in 1973, causing a paradox.

The film begins by depicting the development process that eventually results in the creation of the main character. It is explained that in a robotics laboratory, five androids were created as part of an experiment, each one identified with a different color, but one turned out to be different. The yellow one developed the ability to think and learn, to the point that it escaped the facility in which it had been created and became a part of society for 18 months. Rather than seeing humans as enemies or a threat to its own survival, it was "making decisions, and observing us and learning." A SWAT team is sent after Yellow, chasing him through several countries and finally tracking him down in Shanghai. The film concludes during the encounter between the android and the SWAT team, with a voice over suggesting the birth of a new era, with AI becoming part of our society.
