Janie is not exactly sure why her daddy is riding a bus from Indianapolis to Washington, D.C. She knows why she has to go-to stay out of her mother's way, especially with the twins now teething. But Daddy wants to hear a man named Dr. Martin Luther King Jr. speak and, to keep out of trouble, Janie is sent along. Riding the bus with them is a mishmash of people, black and white, young and old. They seem very different from Janie. As the bus travels across cities and farm fields to its historic destination, Janie sees firsthand the injustices that many others are made to endure. She begins to realize that she's not so different from the other riders and that, as young as she is, her actions can affect change.
