Five years after Godzilla terrorized the city of Osaka, Japanese scientists have developed a sure-fire way to finally destroy Japan's monster nemesis. They have created the world's first man-made black hole, which will trap Godzilla for eternity! But during a testing of this new Dimension Tide, an insect caught in the hole mutates, producing gargantuan eggs that gave birth to a new menace: giant dragonfly monsters called Meganula. Meganula queen, the 50-meter Megaguirus, is also on a hunt for Godzilla, needing to steal his energy to survive. From the sky down to the depths of a city's underground sewer tunnels, Megaguirus, Godzilla, and humankind battle for supremacy. Who will prevail in this high-tech, three way battle of terror and destruction?
