Synopsis:
Kandorian scientist and Supergirl look-a-like, Lesla-Lar, has used a special device to cause Supergirl’s powers to disappear. Without her powers, Supergirl, as Linda Lee, allows herself to be adopted by Fred and Edna Danvers. Superman constructs a hidden closet in her bedroom for mementos of her past deeds.

The jealous Lesla-Lar then switches places with the sleeping Linda Lee, allowing Linda to live her life within Kandor. Lesla then breaks Luthor out of jail and joins him in criminal activities as Supergirl. However, Linda’s memory begins to return when she sees the new Supergirl appear. Lesla returns each of them to their rightful places to preserve her secret, but plans to take Linda’s life again later.
