When newcomer Cheng Muyan joins the workforce, his team leader and colleagues mooch rides from him for an entire year, leaving him to pay more than 30,000 yuan out of pocket with no way to get reimbursed. On the day senior management visits, he covers the company notice board with copies of the receipts and sends a resignation email exposing their misconduct. The offenders are publicly reprimanded across the industry, and their careers are ruined. Cheng Muyan joins a new company and rises to director, only to be harassed by the same two people again. This time, he fights back with evidence and ability, finally ushering in an era of his own.
