In the darkest age of judgement, Post-Godzilla, where humanity is on its last legs towards extinction, something magical happened. Plant-life starts to bloom unexpectedly in the desert, water flows from beneath, creatures walk the earth, nature has been restored, and hope that life would carry on has been answered in the shape of a kaiju, Biollante. Could this be what Godzilla had wanted all along? But before they can jump to conclusions an alien empire of Ghidorahs have arrived to conquer Earth right before it's reborn. Godzilla, Biollante, and other kaiju battle the Ghidorah race before they destroy the world.
