When Nancy Clancy finds out that both her guitar teacher, Andy, and her favorite babysitter, Annie, have broken up with the people they were dating, she decides to make them fall in love on Valentine's Day.

Nancy is determined to make the cover of her very first book report as fancy as she can, but she spends so much time on it that she has no time to write about the book.

Preparing for picture day at school by choosing just the right outfit, Nancy wonders how she should style her hair and considers pigtails, a bun, and long ringlets before formulating a plan that has her reaching for the scissors.

When Nancy, the girl who loves to use fancy words, learns about Earth Day and "being green," her enthusiasm causes problems at home.
