Zhao Feng, a mechanical engineer who stayed up seven consecutive nights to safeguard a multimillion-yuan project, receives a zero-yuan year-end bonus because he was too busy working on-site to attend a company team-building event. He decides to resign, switch off his phone, and catch up on sleep. That very night, however, a sudden malfunction shuts down the client's production line, and the company rushes to his door for help. Zhao Feng identifies the problem and restores production, but even after completing the handover, he remains determined to leave. Introduced by his former classmate Shen Yue, he earns recognition at a new company through his outstanding technical skills, honesty, and sense of responsibility. He leads his team to grow together and finally gets to enjoy a hot meal after work without worrying about being interrupted.
