Three-and-a-half-year-old Sui Sui and her mother, Shen Xiuqin, leave home after a misunderstanding and move into a mountain-keeper's hut. Drawing on the mushroom-growing techniques she learned, her mother starts over from scratch, while Sui Sui helps sell mushrooms, keep count, and design a logo. Zhao Jianguo, a retired agricultural technician, quietly provides technical assistance, and their cooperative gradually gets off the ground. Their mushrooms earn recognition at a trade exhibition. After experiencing setbacks, Zhou Tiezhu returns to the village and settles down to work, learning to take responsibility. Mother and daughter, together with the villagers, support one another and gradually turn their difficult days into a life filled with hope.
