After a lightning bolt zaps a robot named Number 5, the lovable machine starts to think he's human and escapes the lab. Hot on his trail is his designer, Newton, who hopes to get to Number 5 before the military does. In the meantime, a spunky animal lover mistakes the robot for an alien and takes him in, teaching her new guest about life on Earth.
