The result is a magical clock with the power to control time itself, to make years be reduced to seconds and a lifetime to pass in an instant. Refusing to wield such huge power, the King orders Aeschylus to destroy the clock and its plans. That night, however, the magician is killed by orders of evil sorceress Karnissa, who steals the clock and unleashes a curse upon the kingdom. As everyone grows old, James most embark on a race against time to save his land, his love, and the world from destruction.
