As the new millennium approaches, the world keeps giant creatures under control on a secure island called Monsterland. However, this peaceful isolation is suddenly shattered by the threat of an alien invasion. In this science fiction film directed by Ishirō Honda, colossal creatures under mind control target metropolises from Tokyo to New York. In this chaotic world, where the purest form of tokusatsu aesthetics is brought to the big screen, humanity must confront both the threat from the sky and the monsters it has created.
