52-Year-old Lin Wan traveled back to her 26-year-old body (1999) with 26 years of memories, becoming a young mother of two children and a daughter-in-law who was rejected by her mother-in-law. She needs to rely on the golden finger of "knowing everything in advance" to repair the relationship between mother-in-law and daughter-in-law, guide her husband's growth, protect the future of her two children, and turn the broken family into a well-off and happy harbor within two years.
