Bespectacled nerd Li Junwei (Qiao Renliang) and pretty girl Tang Xiaolian (Li Xiaolu) are manning the night shift at the 24-hour Wang Wang Supermarket when balding lottery addict He Sanshui (Xu Zheng) arrives, demanding to speak to the lady owner Wang Sufen (Yang Qing). Wang, who is not in, made a typo entering the lottery number more than a month ago, which rendered He Sanshui's winning ticket useless. When He Sanshui asked for the ¥9500 win at an earlier occasion, she attacked him and drove him out of her store. This time, He Sanshui returns with a stun gun flashlight and his dimwitted cousin He Damiao a.k.a. Tire (Wang Dongfang), and is determined to get his ¥9500 "back".

At this moment, Li's goofy roommate Zhu Liao (Zhao Yingjun) who wants to record a funny prank video also storms in, wearing a pantyhose on his face and wielding a knife, but is quickly tasered down by He Sanshui. He Sanshui proceeds to the cashier counter and realizes there isn't enough cash in the cash register. He and Tire rope up everyone else in the soundproof back room—which has a complete Karaoke system—and taking their place behind the register begin to run the store, funneling the profits into their own pockets.

The hungry Tire is getting preoccupied with bag after bag of junk food (some of which have expired) and Karaoke singing in the back, so Li—whom He Sanshui calls "Little Steel Teeth" because he wears a dental brace—is brought back out to help with the work. Some time later, Tang's escape attempt, during which she tasers down Tire, is spoiled by Zhu's foolishness and He Sanshui's second stun gun.

Wang suddenly returns to the store from her Mahjong games—obvious having lost all her money—and immediately begins to attack He Sanshui with a bag of weight before Tire tasers her down. However, holding her (and her French Bulldog Wang Wang) hostage does nothing to the business, which has been slow tonight. In an effort to boost sales He Sanshui decides to give 50% discount to all store items, and business quickly perks up after a taxicab chauffeur (Cao Li) helps spread the news to his colleagues. During this time, Tang discovers voyeuristic photos of hers in Li's phone and realizes that Li likes her.

With ¥3.50 to go before their ¥9500 goal (taking into account that Tire has eaten ¥118.10 of food), a Guanzhong dialect-speaking, gun-toting robber (Zhang Jiayi) on the run arrives to retrieve a diamond his partner left in the ice in the store freezer. Unable to find his diamond he takes everyone hostage and is in the middle of having everyone strip, when Yaozi (Ye Qian)—the store's delivery man who has fallen asleep in the warehouse—barges out from the rear. The group tries to subdue the gunman, but fails because He Sanshui's stun gun has run out of battery.

When the diamond is finally discovered during the subsequent search, the dog Wang Wang picks it up and runs outside. This is when the gunman realizes that the police have already surrounded the store: it was Tang who secretly texted a policeman shopper (Li Weijian). The gunman runs back inside, grabs Tang and points his gun to her head. Li saves Tang but is shot by the gunman, who is accidentally electrocuted by a loose wire.

Some time later, the policeman returns to the store and learns that Li—no longer wearing a brace and glasses—and Tang have been dating, while He Sanshui and Wang are honeymooning in Hainan. They watch on TV that Zhu has become a famous actor, and Tire his agent.
