Hayley Wheaton doesn’t like being herself…she wishes she were her cool, seventeen year-old sister Alexia. Not only is Alexia the prettiest and most popular girl on the planet, but she’s got Kyle -- the most gorgeous, wonderful guy ever. One night, when Hayley sees Alex and Kyle cuddling happily in the driveway, she looks away to the dark night sky, and spots a falling star. She closes her eyes tightly and whispers, "I wish I were Alexia Wheaton."

And the next morning, she is! She can’t believe her wish has come true, and neither can her sister Alexia, who is now stuck in Hayley’s body. They will have to wish on the same falling star at exactly the same time, in order to change back. But will they ever be the same again?

In the role of Alexia, Katherine takes on the difficult challenge of playing two different personalities taking turns inhabiting the same body.
