Anne Sullivan guides Helen Keller as her teacher within the narrative, focusing on Helen's education following her loss of sight and hearing. She interacts with Helen's family members—Arthur Keller, Kate Keller, and James Keller—and participates in events involving medical professionals like Dr. Alexander Graham Bell and Dr. Kishon. These interactions occur within the historical context of Helen Keller's early life and educational journey. Anne Sullivan's portrayal remains centered exclusively on her professional role and dynamic with Helen Keller during this period. Her personal background, childhood, experiences with visual impairment, educational history, motivations, internal conflicts, or life outside this teaching relationship are not part of the source material's depiction.
