In Zhaoji'ao, where the belief that sons matter more than daughters is deeply rooted, Guiying single-handedly holds together her storm-tossed family, giving all her tenderness and strength to her daughter, Zhaodi, who longs to study.
The mountains are a cage, and prejudice is a freezing night. Zhaodi secretly learns to read behind the woodpile, holding fast to her dream of an education even when all seems hopeless. With guidance from Lin Yan, a teacher sent to the village, she breaks through one obstacle after another and makes her way out of the mountains, growing from an innocent child into an outstanding student.
After years of hard study, Zhaodi finally achieves her dream of attending university. Yet she chooses to leave behind the city's comforts and return home to give back. Together with Lin Yan, she builds a new school and brings hope to the mountains through education. Her younger brother, Mancang, devotes himself to the land and leads the villagers out of poverty. Her second and third sisters use their writing and songs to warm the hearts of children.
This is a coming-of-age epic about a mother's love, perseverance, and legacy, telling the story of ordinary women who find a way through hardship and seek light in the darkness. The mountains were once without a single lamp, but they made love their torch and dreams their guiding light. In the end, their glimmers gathered into a river of stars, illuminating their own way home and the way home for the entire mountain community.
