Allie Aldaine has a secret. A secret identity. It was a pretty good secret, actually, one only her adoptive parents and sister new about. Allie had powers. Super powers. She was indeed fact Supergirl. Yes, the one that flies around wearing red and blue with the big 'S'. The one who has enhanced super hearing, super strength, indestructible, and a red cape. The little sister of Superman, if you will. Sow what happens when Allie Aldaine - aka Supergirl - moves to a small place called Swellview? And bumps into two other superheroes who also happen to red and blue, too?
