Modern girl Yang Tiantian travels back to her mother Su Fei's high school days in the 1990s, vowing to reverse her mother's fate of being persecuted to death by her husband Yang Zhihua and her aunt Su Ping. She first exposed Yang Zhihua for cheating and scored zero in the exam, and then bought fruits to cut off his financial path. When the Yang family and Su Ping colluded to kidnap Su Fei and force her into marriage, Yang Tiantian broke into the scene alone and held a knife confrontation. She called the police in time, and finally rescued her mother, helping her completely get rid of her original family and the control of evil people, and move towards a new life.
