When a rainstorm prevents Nancy and her best friend, Robert, from getting to the planetarium the night of a class field trip, she has a brilliant idea for making things better.
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.
