Chapter one basically describes Helen Keller as a very young child and how she was born into a very wealthy family in Alabama. She was normal in every way until she turned 19 months old, when she had a very high fever that left her deaf and blind.
Chapter Two chronicles the next five years of her life where she lived in total sensory isolation (mostly). She had very limited ways in which she could communicate. Her mother, Kate, doted on Helen understanding some of the ways in which Helen was trying to communicate. But, in the end, Helen was allowed to go anywhere and do anything that she pleased, even to the point of being a holy terror to everyone who lived there.
Chapter Three shows Helen's frustration at not being able to express herself or communicate with others. Her temper rages out of control. Kate read about some work that was being done with deaf and blind children and thus the search began for someone to work with Helen. The family even reached out to Alexander Graham Bell.
Chapter four shows Anne Sullivan's arrival. Right away Ms. Sullivan begins working with Helen to communicate using sign language. Helen views it as a game and nothing more. It becomes clear in this chapter that Helen does not view Anne as her teacher. It was while Helen was having a major temper tantrum that Anne takes her outside for a walk and while there puts cool water over her hands. Anne spells the word WATER and finally thinks click into place for Helen.
