Astronauten Glenn en Fuji onderzoeken Planeet X en ontmoeten mysterieuze buitenaardse wezens die bekend staan als de Xiliens, die de mensen op aarde vragen om hun wereld te redden van 'Monster Zero'. In ruil voor het lenen van Godzilla en Rodan bieden de Xiliens een geneesmiddel tegen kanker aan. Terwijl Glenn onderzoek doet, ontwikkelt hij een romance met juffrouw Namikawa en ontdekt hij de ware bedoelingen van de Xilien.
Nee, helaas is 怪獣大戦争 nog niet beschikbaar op Netflix in Nederland.
