He is plunged into a world of shadow in which he will have to learn to eat, dress himself, read and summon up his courage before going back to school with the white cane he hates so much. His life has changed completely and little by little he will have to learn how to fend for himself with the help of a guide dog, who takes him to meet Blanca.
