Marta (Lucie Patikova) was blinded in an accident brought on by her careless and indulgent younger sister. Now in a school for the blind, Marta keeps up her hope that she will one day see again, mainly because her mother - out of good intentions - has led her to believe that the blindness is only temporary. Before long, Marta comes to realize that her condition will last until she dies, and she begins to despair, hating her mother for giving her false hope. Only a dedicated psychologist, Dr. Mos (Oldrich Navratil) seems to have the means of retrieving Marta from her depression.

A stories about friendship and love, children and parents, students and teachers - all from one regular Czech school during the eighties.
