Atsuko "Akko-chan" Kagami (known variously as "Stilly," "Caroline," or "Julie" in Western versions of the anime) is an energetic elementary school girl who has an affinity for mirrors. One day, her favorite mirror which was given to Akko by her mother (or in some versions, by her father, as a present from India) is broken, and she prefers to bury it in her yard rather than throw it to the trash can. In her dreams, she is contacted by a spirit (or in some cases the Queen of the Mirror Kingdom) who is moved that the little girl would treat the mirror so respectfully and not simply throw it away. Akko-chan is then given the gift of a magical mirror and taught an enchantment that will allow her to transform into anything she wishes.

From the TV series of "Astro Boy," three episodes were selected for theater re-edition, "Robot Rocket" (46th episode), "Earth Defense Troops" (56th episode) and "The Last Day of Earth" (71st episode). Of these three, "Earth Defense Troops" was the only one originally derived from Tezuka Osamu's story "Number 7." Its settings were diverted to the "Astro Boy" series. In this film, the whole scene of "Earth Defense Troops" and a part of "The Last Day of Earth" were reproduced in color for this theater version.
