In the 1970s, rural daughter-in-law Lin Wan suffered years of harsh treatment from her in-laws. To ensure her daughter could eat her fill, she took a risk and secretly raised loaches using ancestral folk methods. Along the way, she faced continuous hardships such as being reported by others and her loaches falling ill. Her husband finally came to his senses and stood up to protect the mother and daughter. After the policies opened up, Lin Wan took the lead in organizing villagers to farm together, overcame heavy crises, led the entire village out of poverty to become wealthy, and achieved a dual comeback in family and career.
