Sissi Fischbacher, a 30 years old woman will soon be teacher for rehabilitation for blind persons: her last test will be to take care for a 60 years old Swedish businessman, Theo Olsson who became blind after an accident. Theo has been an authoritarian manager of a great steel factory and now he has become bitter and solitary. The first contacts between Theo and Sissi are quite tense. He is arguing that he can manage his situation without help. Sissi will not give up her duty. Both are very stubborn persons, but little by little Theo learns to walk safely through his house, he is sometimes desperate and Sissi has to remember him to be more patient.—zutterjp48
