Percy is just a normal shepherd boy with an overbearing mother, when a chance encounter with a knight inspires him to take on the quest for the Holy Grail! But when he presents himself at Camelot, the knights and ladies all laugh at him. He meets Princess Blanche, who asks him to help her with the curse on King Arthur before trying the Grail quest, but when he fails the curse quest, Percy loses hope. He tries to play cool with the knights and ladies of Camelot, until his friends make him realise meanness doesn’t suit him either. Owning up to his faults and apologising to his friends, he is rewarded with the Holy Grail. But then he has to figure out how to use it to set everything right in the kingdom.
