Lin Tao takes home leave once every half year, and as soon as he returns to the village, he is intercepted and falsely accused by Zhou Xiaodong and his father of a hit-and-run on the provincial highway, demanding compensation. The villagers mistakenly think he is a freight driver and chime in with accusations. In reality, Lin Tao is a high-speed train driver who was on duty in the cab on the day of the incident, and he doesn't even have a motor vehicle driver's license, instantly pulling out his duty scheduling records and traffic management credentials to prove his innocence. Tracing the clues, he discovers that the mastermind is the village tyrant Ma Desheng, who has been eyeing his family's old street-facing house and wants to use the false accusation to extort money and force relocation. Through several rounds of maneuvering, Lin Tao submits evidence to expose the conspiracy, legally protects his family's old house, and brings punishment to those with malicious intentions.
