In the 1968 film "Destroy All Monsters," a race of malevolent aliens called the "Kilaaks" release giant monsters across the world, forcing authorities to investigate their potential weaknesses and regain control of the monsters. As the monsters wreak havoc on major cities, Dr. Yoshida of the UNSC orders Captain Katsuo Yamabe to investigate Monsterland, where they discover the scientists have become mind-controlled slaves of the Kilaaks. With the help of the crew of his spaceship, Moonlight SY-3, Yamabe must stop the Kilaaks' plans and defeat the monstrous threats, ultimately leading to the defeat of King Ghidorah and the return of the monsters to Monsterland.
