Fancy Nancy and her father love stargazing, and during her first campout under the stars she describes the heavens to him and her sister, JoJo, using her fancy words.
Nancy, who likes to use fancy words, is dismayed to be partnered with shy classmate Lionel for the school talent show until she comes up with an act perfectly suited for both of them.
Nancy is delighted that the new boy in her class is from Paris and sets out to become his friend, then discovers that this Parisian is not quite as fancy as she had thought.
