The day has come to an end and the castle is closed to the town people, but Princess Claire has just met Ninian, a young man from the village, in desperate need of the king's help. His father is ill and the family cow has wandered over a broken fence and eaten the neighbor's corn. Now the neighbor won't let the cow go. Without the cow, the young man's family has no milk, or cheese or butter to sell for food. Can the Princess get her father to help Ninian in time?
