Lin Xiao co-runs a supermarket with his girlfriend Cui Xiaoxiao and close friend Wu Zhi, but is framed by the two and sentenced to three years in prison over an accident.
Upon his release, Lin Xiao finds the pair have become a couple and built a highly successful supermarket using his original business strategies. To stage his comeback, he opens "Pangpang Supermarket" right nearby with new partners Lin Xue and Ma Dong, centering his business on four customer-first principles. The store runs at a loss initially amid multiple challenges.
The turning point arrives when an elderly customer accidentally shatters a 2,000-yuan bottle of Moutai. To everyone’s shock, Lin Xiao waives all compensation and even gifts her eggs as consolation for the fright. A bystander films the incident and shares it online, making Pangpang Supermarket go viral for its thoughtful service, and its shelves are soon emptied by crowds of customers.
Envious, Cui Xiaoxiao and Wu Zhi attempt to sabotage the store, but their schemes backfire
