Within medieval Balkonia lives an evil king who rules with fear and ferocity.

Meanwhile, unbeknown to Garth (a young boy living with his kindly grandparents), a magical sorcerer has imbued his sister with a great gift: the ability to read people's minds and hearts. One day the king's soldiers visit the home of Garth's grandparents, demanding they pay the king's tax. While searching for money, Garth stumbles across an old letter hidden within a box under his grandparents' bed. The letter not only reveals the truth behind Garth's parents' untimely demise, but also a quest that he must undertake to find his missing sister - a sister he never knew existed. Accompanying the letter is a mysterious pendant. What does it signify?

As the brave young boy sets out to fulfil his parents' final wishes, he is accompanied by a friendly furry troll who proves to be far more than the fabled beast beneath the bridge...?
