Ordinary worker Xu Liunian faces an unusual perk: a free chartered bus ride home. But he remains alert, daring to question the bus company, the route, and why everyone's identity cards are needed. When his coworkers go missing, he cooperates with the police, disguises himself to return to the company, and ventures into danger to pinpoint the location of the people being held captive. Ultimately, he helps the police rescue everyone and bring the criminals to justice. The story conveys an inspiring message: when an unexpected 'good deal' comes along, ask a few more questions; when faced with injustice, trust the law and use your intelligence. Ordinary people who stand by their principles and help one another can also become a beacon of hope for others. Genuine goodwill can withstand scrutiny, and our legitimate rights must be protected through reason and the rule of law.
