A.I. Artificial Intelligence

In the late 22nd century, rising sea levels from global warming have wiped out coastal cities such as Amsterdam, Venice, and New York and drastically reduced the world's population. A new type of robots called Mecha, advanced humanoids capable of displaying thought and emotion, have been created.

In Madison, David, a Mecha that resembles a human child and is programmed to display love for his owners, is given to Henry Swinton and his wife Monica, whose son Martin, after contracting a rare disease, has been placed in suspended animation and is not expected to recover. Monica feels uneasy with David, but eventually warms to him and activates his imprinting protocol, causing him to have an enduring childlike love for her. David is befriended by Teddy, a robotic teddy bear that belonged to Martin.
