In this [[Direct to Video|direct-to-DVD]] movie, [[Barbie]] and Teresa tell Stacie the story of two best friends, Liana and Alexa. Although the two girls do not have much, they have each other and a love of music. It gets worse when a nasty storm destroys all the flowers they would usually sell, but an act of kindness grants them a mirror. Inside the mirror dwells apprentice muse Melody, who used the mirror as a means of escaping evil muse Lydia, who intends to grab the key to the muses' Diamond Castle and plunge the world into a state of grim darkness.
