Отчаяната битка на човечеството за възстановяването на Земята от Годзила продължава. Ключът към разгромяването на краля на чудовищата може да бъде Мехгодзила, роботизирано оръжие, за което се смята, че е изгубено преди близо 20 000 години.

An Okinawan prophecy that foretells the destruction of the Earth is seeming fulfilled when Godzilla emerges to return to his destructive roots. But not all is what it seems after Godzilla breaks his ally Anguirus's jaw. Matters are further complicated when a second Godzilla emerges, revealing the doppelgänger as a mechanical weapon.

Mothra and her fairies return to Japan to warn mankind that they must return Kiryu to the sea, for the dead must not be disturbed. However Godzilla has survived to menace Japan leaving Kiryu as the nation's only defense.
