In her past life, daughter-in-law Zhang Lan toiled all her life, pouring everything into her foster son Chen Yang, only to be met with cold indifference and taunts about "boundary sense." When her husband passed away from a myocardial infarction, she jumped from a building in grief. After her rebirth, she returned to the day her daughter-in-law came over to set rules, watching coldly and launching a decisive counterattack to take back the wedding house and bride price, drive away the ungrateful wretch, and expose their double standards. Faced with Chen Yang and his wife's parasitism, threats, and cyberbullying, she teamed up with her nephew Cheng Huan to reverse public opinion, notarize her inheritance, and completely cut ties. In the end, she traveled the mountains and waters with her husband Lao Chen, enjoying a happy rest of her life.
