Terasawa, an author of books on psychic phenomena, thinks he’s discovered the real origin of Godzilla. During World War II, a group of Japanese soldiers stationed on Lagos Island were protected from harm by a giant dinosaur called a Godzillasaurus. The soldiers left near the end of the war, and the island was destroyed by a hydrogen bomb test in 1954―just months before Godzilla first attacked Tokyo.
Shindo, the commander of the troops on Lagos, is now a powerful businessman who denies any knowledge of the dinosaur.
Meanwhile, a UFO lands on Mt. Fuji. When the army investigates, they are greeted by holographic projections of the UFO crew, which consists of an android, two Caucasian males―Wilson and Gurenchiko―and an Japanese woman named Emmy.
The visitors, called the Futurians, explain that they come from the year 2204, a time long after Godzilla has destroyed Japan completely. The Futurians explain that they can go back to the 1940s and teleport Godzillasaurus to another island―thereby avoiding the creation of the mutant monster Godzilla. As proof of their story, they show the Japanese government a time-worn copy of Terasawa’s Godzilla book, which the author hasn’t even written yet!
Terasawa, psychic Miki Saegusa, and Professor Mazaki board the time machine and travel back to Lagos, where they witness the U.S. invasion in 1944. The Americans are repulsed by the Godzillasaurus, which is gravely wounded.
After the Japanese troops leave―led by a young Shindo―the Futurians teleport the dinosaur far from Lagos, then return to the present. But the Futurians had taken along three strange, golden birdlike creatures called Dorats, which they released on Lagos before departing for 1992.
When the time travelers return, they learn that Godzilla has vanished. It’s as if he never existed. But a new menace has appeared, a three-headed monster called King Ghidorah. It looks suspiciously as if the tiny Dorats have mutated into a single, gigantic creature.
Emmy discovers that her fellow time traveler Wilson controls Ghidorah, from the time ship. She secretly reprograms the ship’s android to help her and warns Terasawa of the Futurians’ plan. The time travelers issue an ultimatum, but Japan refuses to surrender.
Shindo, meanwhile, believes that Godzilla can be re-created. He has built a nuclear submarine that can be used for that very purpose. But on its mission, the sub is destroyed―by an even bigger and meaner version of Godzilla.
Terasawa learns that a Russian nuclear sub sank in that same region, probably giving off enough radiation to create Godzilla anew.
Godzilla comes to Japan and makes short work of Ghidorah, blowing off its central head. Then Godzilla turns on the Futurians, destroying their time ship.
Emmy escapes to the future in a time shuttle, where she retrieves the body of Ghidorah and creates the cyborg Mecha-King Ghidorah. She returns to 1992 just in time to battle Godzilla in the heart of Tokyo.
Emmy carries Godzilla off and drops the monster and Mecha-King Ghidorah into the deepest part of the ocean. Then she emerges from the water in a time shuttle. Before departing for the future, Emmy informs Terasawa that she is a descendant of his.
