His misguided priorities are soon challenged when he encounters a mysterious little girl. That girl takes Dickens on a strange and moving journey in which he is shown the future he could have if he doesn't change his ways and, more importantly, he is shown a better purpose for his writing as a way of speaking for the oppressed who need his help. It is these events and lessons that would inspire Dickens to write an extraordinary Christmas tale that would become his greatest work, A Christmas Carol.
