After Zhou Guifang passes away, the Lin family quarrels over her inheritance. Her granddaughter, Lin Xiaoman, gives up a high-paying job and receives only a noodle recipe. Ridiculed by her relatives, she opens a noodle shop with just 3,000 yuan, only to discover that the account book has been switched and the property and savings listed in it are all fake. Her uncle, Lin Guoqiang, and aunt, Lin Meijuan, try to keep the inheritance for themselves. However, during seven family banquets prepared according to Grandma's recipes, old secrets come to light: Grandma had secretly paid off her uncle's enormous debts, her aunt's marital debts, and the compensation owed for her father's workplace injury. The supposed million-yuan savings were actually a record of debts repaid, and the ancestral home had already been sold, leaving only the right to live there. Grandma's true inheritance consists of three debt-clearance certificates and a recording revealing how she spent her entire life supporting her family. When the truth is finally revealed, the family regrets its actions, and the relatives are ultimately reconciled.
