Samson is an Old English Sheepdog puppy, born to a present-day family who live in their old family castle in the English countryside. Raised on stories of courageous dogs and noble heroes of old, Samson dreams of being a heroic knight. When he is finally old enough to explore on his own, Samson looks for adventures worthy of a knight. He meets the wild creatures living near the castle and makes many new friends, but he fails to do anything heroic. Or does he?
