The true story of darkness of Helen Keller that, since infancy, never seen the sky and this lonely world of silence, heard her mother's voice or expressed her innermost feelings. Then a 20-year-old teacher from Boston, Annie Sullivan, arrives. Having just recently regained her own sight, the no nonsense Annie reaches out through the strength of touch to Helen, the only tool they have in common, and also directs her pupil on a miraculous journey from isolation and fear for light and pleasure.
