In England at the dawn of recorded history, a King prepares to defend his castle against an invading Saxon army. There are spies behind his walls and a blood oath has been sworn against his son and daughter. To spare their lives, he sends them on a journey through the wilderness to the kingdom of his cousin. They carry with them a plea for help, and the last hope of the Celtic peoples south of the great Roman wall. To protect them on their journey, the king calls upon a mystic warrior, his giant friend and a servant to the princess who is small in stature but mighty in courage. As they travel, they are pursued and attacked by powerful forces, bent on their destruction. But just as it seems there is no hope, they are joined by a wizard of the forest possessed of great powers unknown to mortal men. He knows the princess carries with her a priceless, ancient gift that must not fall into the hands of the enemy.
