Patlabor cops Noah Izumi and Azuma Shinohara are called in to investigate, and soon find themselves trying to decipher the apocalyptic visions of E. Hoba, who wrote the operating system for the Labor robots and then committed suicide. Hoba introduced a virus into the software that could affect robots all over world and cause unparalleled destruction. In abandoned slum apartments and high-tech construction sites, he left clues about what he was doing--and why. But are Noah, Azuma, and their friends clever enough to second-guess a genius? And will their superior officers accept their conclusions?

The first Patlabor feature has a darker tone and look than the previous OVA series. Oshii assumes the viewer already knows the characters, and doesn't bother introducing them. But this powerful tale of the dangers of over-reliance on technology is far superior to ordinary mecha features. The recent attacks of powerful computer viruses give the story an added relevance.
