 Astro fights to free abused robots from a robot theme park that masks a secret weapons factory; Astro and fellow robots are stranded on the moon only to discover a valley full of diamonds... but they are not alone, and the diamonds are not unguarded.
Then Astro becomes trapped in the twentieth century after a child prodigy's time machine breaks down; and Professor Ochanomizu and Astro Boy are caught up in a movement to overthrow a dictator who has a machine capable of producing human clones...and a force of evil robots to defend it!
