On Mother Zhao Yufen's sixtieth birthday, eldest daughter-in-law Xu Man, suspecting her mother-in-law of favoritism, overturns the dining table in public. Father Lu Jianguo immediately decides to divide the family property the next day. Xu Man's family is forced to move out, while second daughter-in-law Bai Yiyi stays behind with fake filial piety, secretly eyeing the old house demolition compensation and her mother-in-law's private savings. Daughter Lu Yao accidentally discovers an account book her mother Zhao Yufen kept for twenty-six years, containing 1.05 million in deposits and nearly 5 million in financial management funds. After learning about it, Xu Man brings a lawyer to sue, ultimately losing the lawsuit; Bai Yiyi picks the lock in the middle of the night to steal the account book and is caught red-handed by the surveillance cameras. As the truth is revealed, Xu Man comes to her senses, and Bai Yiyi leaves with nothing. The old house demolition yields 4.22 million in compensation, the mother fairly distributes the money, and the family guards their conscience and home.
