The terrible and trecherous Pendragon plans to gain the throne of Cornwall by getting the king to abdicate and to marry his lovely daughter. To help him he has his dreadful witches in his castle and his almost unstoppable sorcery. A giant under his control abducts the princess, but on the way home with her the giant meets farming lad Jack who slays him. This is only the beginning.
