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?
