Gloria Sloane encounters a white deer in the Snowpeak Range while trying to save her blind granddaughter Nina. The deer states it can only save one person, and Gloria resolutely chooses her granddaughter, sending Nina to Snowveil Valley to learn skills for two years. In the darkness, Nina learns to rely on hearing, smell, and touch, gradually becoming independent. Two years later, her eyesight is restored, and she steps forward during an avalanche crisis to lead villagers to safety. Eventually, she opens a small medicine shop, where she stays with her Grandma while also gathering medicinal herbs in the mountains. The story conveys that love means letting go, allowing children to walk their own path, and learning to be grateful and protective of others.
