In an annual event at Midvale Orphanage, the orphans are given temporary jobs, allowing them to earn money and learn a trade. Linda Lee, aka Supergirl, becomes a temporary cub reporter at the Daily Planet. There, she's assigned an article on Superman's five greatest feats.
Meanwhile, another Supergirl appears, claiming to be from the planet Krypton. Investigating, the real Supergirl discovers that the fake isn't the Linda Lee robot, and it isn't her under hypnosis or something. So when this "Supergirl" visits the Daily Planet, Linda Lee tricks her by giving her a fake Kryptonite meteorite. When the false Supergirl reacts with pain to the Kryptonite, Linda Lee reveals that the "Kryptonite" is really green cardboard, exposing the fake Maid of Might.
The fake is revealed to be one of several similar-looking publicity agents around the world, hired by Ace Studio, a movie studio, to promote their upcoming film "The Supergirl from Krypton". In the story, Supergirl comes from the Kryptonian city of Toz. Her ship was blasted off of Krypton with her in suspended animation, and the ship stopped working and circled the Earth for several years before a glancing blow from a meteoroid made it work again. During the film, Supergirl fights a dragon.
Much later, Linda attends a private screening of the film at Midvale Orphanage. Afterwards, she overhears some boys talking about how cool it would be if there were a Supergirl on Earth pretending to be an ordinary girl at the Orphanage; Ernie suggests Linda Lee as a possibility. (Perhaps implying that he has a crush on her, though this is not directly stated).
