The chairman of the group saw that the company's employees were bullying the migrant workers, so he aggressively took action to ask for wages for the migrant workers in order to eradicate the bugs in the company. After learning that some employees in the branch were seeking power for personal gain and even fighting against security guards, they hid their identities and pretended to be security guards to find out. They met employees who looked down on others and not only failed to abide by company rules, but also made sarcastic insults. They even met a snobby girlfriend in front of them. In the end, they revealed their identities, which made these people regret it and successfully eradicated the company's cancer.
