Synopsis:
Linda Lee gets a summer job at the Daily Planet. While working, she learns about a Supergirl that has been seen around the world. At first Linda believes it might be her robot, but she is able to discount this possibility. In case Red Kryptonite has affected her, she locks herself in a safe, but the Supergirl appears again.

The next day the Supergirl arrives at the Daily Planet to do an interview. Linda tricks her with a fake Kryptonite meteor into revealing that the Supergirl is a hoax. A movie studio has made a movie about a Supergirl from Krypton and the super stunts were done as a publicity stunt. When Superman returns from a space mission, he is proud of how Linda exposed the hoax.
