In the midst of Tokyo's urban revitalization, the ambitious Babylon Project is underway, reshaping the city with artificial islands and advanced robots called Labors. However, when a key Project figure's suspicious suicide raises questions, Captain Kiichi Gotou's Patlabor team steps in to investigate. As Labors malfunction and a rogue AI threatens Tokyo, pilot Noa Izumi and her Patlabor Alphonse race against time under Gotou's command to thwart a dangerous conspiracy with apocalyptic implications.
