As a group of astronomers watch the skies for UFOs, a meteor shower deposits an object in Kurobe Gorge.
Meanwhile, Japanese intelligence has learned that Princess Salno is about to be assassinated on a state visit to Japan. If she dies, it is feared that her country will turn to Communism. Detective Shindo is assigned to protect her, but the princess’s airplane blows up in midair and she is presumed dead.
Sindo’s sister works for a sensationalistic television show. She gets a tip that a mysterious prophetess who claims to be from Mars is warning everyone who will listen that a horde of monsters is about to terrorize mankind. When Shindo sees a photo of the Martian woman, he recognizes her as the princess.
Soon the Martian woman predicts the return of Rodan, and the creature appears from the heart of a volcano. Godzilla, she says, will be next. But she also warns that a more terrible monster than either of them will arrive from the depths of space, a monster called King Ghidorah.
The assassins, meanwhile, have also recognized the princess. They return to kill her just as the meteor releases King Ghidorah, which ravages Japan.
Finally, Mothra and the Shobijin convince Godzilla and Rodan to fight King Ghidorah. In a battle royal, the three-headed monster is defeated. An assassin’s bullet grazes Princess Salno’s head, and after Shindo saves her life, the princess’s memory is restored.
