Becca is the pride of her little village until the day the wicked Trolls come down from their mountain and steal her away. The Troll king loves Becca's singing, so he takes her home and locks her in Fang Tower, where she has to sing for him whenever he wants.
Zander wanders the seas fighting pirates and looking for adventure. When he hears the sweet, sad voice of Becca floating down from Fang Tower, he knows he must rescue her.
The Troll king's price for releasing Becca may be more than Zander is able to pay, but he sets off on the adventure of a lifetime to win the treasure the Troll king demands.
