Jiang Zhou works hard for his brother-in-law for three years, turning a failing burger shop into a chain brand, only to have all his achievements stripped away due to a "employment contract", receiving a mere fifty thousand yuan as a humiliating payout. Armed with three business notebooks, he opens a nine-yuan-nine burger stall in a university town, selling only 13 orders on the first day. Using real business operation data to shoot short videos, he goes from being cursed as a "beggar" to selling 611 orders in a single day, ultimately acquiring his brother-in-law's bankrupt brand for two million yuan and establishing a new system of "no management fees unless stores are profitable". From having everything taken away to a triumphant return, he makes those who hurt him watch his comeback with their own eyes.
