Ep 10. Planet X

Four people - a tall, skinny newspaper reporter; a short, fat doctor; a female jazz singer; and a mischievous little boy - are summoned by note to meet at eight o'clock in the park one night. Each arrives to the surprise of the other. But each is even more surprised to learn from Astro Boy that he is the author of the mysterious notes. And to top it all off, they are shocked to learn from the little robot that they are not on the planet earth at all, but on Planet X, millions of miles away from home! All four persons had been unwittingly rendered unconscious by the creatures from Planet X and transplanted on that strange planet in a town that was actually a recreation of their home town on earth. There they were being studied - secretly observed like guinea pigs in a huge laboratory - by the creatures of Planet X, who planned one day to set up their own colony on earth. Escaping that planet and returning the "guinea pigs" to earth proves to be one of Astro Boy's most harrowing assignments.
