Ogasawara is also where all the world's monsters, including Godzilla and Rodan, have gathered for study and to keep them from wreaking havoc on the world. However, a group of alien women known as Kilaaks take over the island and put the monsters as well as the humans under mental control in order to conquer the rest of the Earth. It is up to astronaut Katsuo Yemabe and his crew to stop the Kilaaks as well as release the monsters and the humans from their control before it is too late.
