Blind and deaf since early childhood, seven-year-old Helen Keller is trapped in a terrifying, lonely world of silence and darkness: she has never seen the sky, never heard her mother's voice, never been able to express her deepest feelings. But then Annie Sullivan, a young teacher from Boston, takes her under her wing. Using only the sense of touch, the only sense they share, Annie manages to break through Helen's isolation. Guided by Annie, her courageous student embarks on a journey full of wonders – from fear and loneliness to light and happiness.
