Synopsis:
Wanting a home of her own, Supergirl constructs a Fortress underneath the Arabian Desert. However, an archaeological expedition stumbles across the Fortress on one of their digs. They learn of Supergirl’s existance, but the leader of the expedition, Professor Brant, hypnotizes the other members into forgetting what they have found.

Having learned Supergirl’s secret identity, Brant and his wife adopt Linda Lee. Brant tricks Linda into gathering precious jewels for him. When Linda catches on, Brant blackmails her into building him an emerald palace.

After the completion of the palace, Streaky, having regained super powers, arrives. An accidental dose of his X-ray vision causes the Brant’s to get amnesia. Supergirl destroys the palace and her Fortress. The Brants return Linda to the orphanage, having forgotten all that has happened.
