No biz like show biz

When Miriam gets Suzanne's role in the school play (that is, the role Suzanne thinks belongs to her), Katie knows there will be trouble. But she certainly doesn't plan on being involved in it! Unfortunately, the magic wind has plans of its own—it turns Katie into Miriam just before the show! Katie doesn't know the lines and she can't sing. Will the show go on? Will it go on with Suzanne instead?
