Zhang Lihong parachutes into Xingcheng Company as its new director and introduces a series of outrageous rules: timed bathroom breaks, arbitrary fines and performance deductions, canceled employee benefits, and collective punishment. She treats employees like interchangeable parts on an assembly line. Faced with this oppression, operations specialist Lin Mo refuses to confront her impulsively. Instead, he quietly gathers evidence and joins forces with Chen Xiaoran and other colleagues to stand their ground and fight back using labor laws. After labor inspectors arrive to investigate, Zhang Lihong's violations are exposed, forcing her to resign. Lin Mo earns a promotion into management through his abilities, establishes an employee representative group, reforms the company's management system, and protects workers' rights.
