Hungry for adventure, Thor secretly embarks on the journey of a lifetime, joined by his loyal brother Loki, whose budding sorcery equips him with just enough magic to conjure up trouble, along with the Warriors Three – a band of boastful travelers reluctant to set sail on any adventure that might actually be dangerous. But what starts out as a harmless treasure hunt quickly turns deadly, and Thor must now prove himself worthy of the destiny he covets by saving Asgard itself.

Liana and Alexa (Barbie and Teresa) are best friends who share everything, including their love of singing. One day while walking through the forest home from the village, the girls meet an old beggar who gives them a magical mirror. As they clean the mirror and sing, a musical apprentice muse named Melody appears in the mirror’s surface, and tells the girls about the secret of the Diamond Castle.
