The kingdoms of IT and DUN exist side by side, yet neither knows about the other. It's only when a terrible illness threatens the kingdom of DUN that the princes Lugh, Robyn, and Sampson must venture beyond the borders of their land in search of the one thing that might save their people. When they enter the kingdom of IT they discover a land entirely unlike their own. Though they have their mission to carry out for their own people, they find that IT is in need of heroes as well.
