The real Supergirl had been filming a Kandorian movie in a Supergirl costume, and she bumps her head when she appears in the Fortress. Without he powers, she is vulnerable and the bump causes her to forgot her Kandorian experience.

Superman returns and learns that Linda has again lost her powers. He takes her back in time, where they appear once again. Supergirl helps a small town which is experiencing a plague. Her good deeds are interpreted as witchcraft, and when she returns to the present, she finds a picture of herself in an old book about a witch. Once back in the present, her powers again disappear due to Lesla-Lar’s machine.
