Synopsis:
Linda Lee visits the Daily Planet for a school project and meets with Clark Kent who, as Superman, has been trying to restore her powers. When she returns home that night, Lesla-Lar exchanges places with her and once again visits Lex Luthor as Supergirl. Lesla meets Superman who does not realize that she is not the real Supergirl. She tricks Superman into believing that he has restored her powers and then upstages him in some rescues. Superman decides it is time to tell the world that Supergirl exists, while Lesla schemes to destroy him.
