Synopsis:
Superman has decided to reveal Supergirl’s existance to the world when he and Krypto return from a mission in another dimension. While he is gone, a ring of Kryptonite dust surrounds the Earth, causing Supergirl to retreat under the oceans. From long distance, she keeps her eyes open for crooks on the surface who believe that Superman is helpless. When she stops them, they believe it is Superman acting from underwater.

Eventually the Kryptonite dissipates and Supergirl returns to the surface. The Man of Steel returns as well, but when he tells Kara it is time to reveal her existance, she discovers her powers have disappeared. Superman checks her out and discovers that the power loss is permanent. Heartbroken, Supergirl returns to the orphanage, unable to be revealed as Superman’s secret weapon.
