Star Movie Network-Synopsis: It tells the story of Milo (Feng Hairui), a big man from a poor family, who lost the stock market with his good friend Qiao Ying (Chen Meiyi). As a result, he went to Balcony, a junior public club run like a nightclub, to make money. Under the leadership of Joey's mother (Chen Jieling), he accompanied the host with Feifei (Tongan) and Sabrina (Zhong Zhuofei) every night. Securities analyst Steve N (played by Li Renshen) was brought to Balcony by rich second-generation Lucas (played by Mai Zile) in the task relationship, and saw bankers Lunye (played by Li Kaixian) and Ajie (played by Chen Yongqian). Stephen met Milo on the first day of the mission in Balcony for the first time and carried out each other. Qiao Ying, who passed the brokerage examination, hoped to allow Chen Jie to open an account, while Lucas felt for Joey's mother without being frustrated, while Lunye had a favorable opinion of Feifei. However, under the stock market, there is a hidden surge, affecting the fate of all.

Their monthly income is tens of thousands of Hong Kong dollars, and they have to give it to their mommy and buy high-end cosmetics. Even the time when sex workers talked on the 10th many years ago (all supervised by Wu Jianxiong) was not as good as that. Ah, life is not easy!
