Doc Baker hires a university-trained doctor named Caleb Ledoux. However, Dr. Ledoux is black and – with the exception of the Ingalls – finds very little work because of his skin color. Even Doc Baker is prejudiced and gives his new assistant menial tasks. Later, when Doc Baker is unavailable for a call, Dr. Ledoux is called on to save a pregnant mother having complications during childbirth. He saves her life by performing an emergency cesarean section, and Doc Baker realizes the doctor had training he does not possess. An angry Dr. Ledoux threatens to leave, but only upon Doc Baker's impassioned plea does he decide to stay. The residents of Walnut Grove decide to welcome Dr. Ledoux.
