Nightclub is a comedy film produced by Beijing Orange Tianhuayin Music Production Co., Ltd., which is directed by Qing Yang and starring Xu Zongheng, Li XiaoLu, Kimi and Zhang Jiayi.

The story takes place in a small supermarket that is open 24 hours a day. Li Junwei is a night clerk in a supermarket. He is taciturn in appearance and secretly likes his colleague Tang Xiaolian. They work the night shift together today. Two months ago, He Sanshui bought a lottery ticket in the supermarket and won the grand prize of 9500 yuan, but the prize was ruined because the supermarket owner mistyped a number. Brother Shui, who went to the supermarket to ask for an account, broke into the store with a slightly retarded cousin and began to get back the bonus. Neither Li Junwei nor Tang Xiaolian can solve this problem, but He Sanshui has made a strange decision-he wants to stay in the supermarket aboveboard and sell things to earn his own money. An angry wanted robber appeared in the supermarket. ...

A good friend who came to the supermarket to practice robbery for filming, a color fan named debt collection who looks like robbery, plus a real robber, three groups of fake real "robbers" * * * staged an ironic and funny drama, a beautiful female cashier, a kind and wooden male cashier, a passerby who wants to be red, a middle-aged proprietress wearing a fake hood, and customers who came one after another.

Several people staged a farce this evening, and at the same time experienced a series of ups and downs such as disgust, sympathy, mutual understanding and building feelings. In the meantime, endless accidents and surprises make the whole process full of variables and banter, which makes people laugh.
