Official Trailer Barbie and Teresa in The Diamond Castle

Liana and Alexa are two friends who share a love for music, and live in a cottage where they grow and sell flowers for a living. One day, they find two heart-shaped stones and make them into necklaces to symbolize their friendship. That evening, a storm occurs, destroying their garden. The next day, Liana offers her food to a poor, old woman who gives them a mirror in exchange. Later, the two hear a voice from the mirror and find a girl inside it named Melody. The trio bond over music and Melody teaches them a song; but they are soon attacked by a dragon named Slyder. They manage to escape him, but their cottage catches fire and burns down.
