Li Shulan accidentally encountered a car accident on her way to vacation. She found that she had traveled through time and became the evil mother-in-law in 1973. Li Shulan activated the good mother-in-law system, treated her educated youth daughters-in-law Meng Yue and Su Xiao well, repeatedly fought against framers, and recovered her abused brother Goudan (renamed Li Mingliang). Her daughter-in-law got pregnant and got a villa, and started a happy life.
