A retired senior department head moves in with his son's family, unable to let go of his old habit of ordering subordinates around, so he sets arbitrary rules at home and constantly picks on his daughter-in-law. Unexpectedly, the daughter-in-law used to be a Fortune 500 supervisor and refuses to put up with his behavior. Without arguments or tantrums, she uses logic and established rules to shut down all his unreasonable demands. Later, the father-in-law loses all his retirement savings in a financial scam. The daughter-in-law sets aside past grievances and uses her professional expertise to help him recover all the lost funds. The whole family eventually resolves their conflicts and lives in harmony.
