Earth’s sea levels are slowly rising and coastal cities around the world have been forced to resort to drastic measures to keep floods of Biblical proportions at bay. Nowhere has the need been more desperate than in Japan, where the city of Tokyo has launched the massive Babylon project: a land reclamation undertaking so vast that it can only be completed with the aid of human-piloted construction robots called Labors.
Unfortunately, any invention can be used for good or for evil, so to keep the Labors from being misused, the Tokyo police maintain their own units of Patrol Labors. Now the officers of the SV2 are about to receive their ultimate trial by fire, as multiple waves of Labors begin to mysteriously go berserk all at once. As the armored blue line fights to maintain control of the resulting chaos, they must also solve the mystery behind the outbreaks.
Are they random? Are they tied to the construction of Babylon itself? Or is there a human element secretly orchestrating the ultimate destruction of the entire city? The wrath of nature and the gods is unleashed and only the courage of a handful of brave men and women can save the city in Patlabor – The Movie!
