Retired senior accountant Chen Guodong discovers that his son-in-law Zhao Lei has forged his identity to apply for a loan, and has also long demanded pension funds to fill family financial gaps. He produces years of preserved transfer receipts and pre-marital loan agreements to legally clarify family debt boundaries and terminate unreasonable financial support. His daughter Chen Xiaoman suddenly wakes up and confronts marital problems, and the old man ultimately guards his later-life savings and bottom line of living.
