Chen Wangzhou, a former racing champion, retired and concealed his identity, working as a humble mechanic at a repair shop in Shenjia Village. Five years later, the repair shop faced a crisis when the Feiqi Racing Team tried to forcibly take over the village's mountain roads for training and challenged the villagers to a racing competition. In the end, Chen Wangzhou stood up for Shenjia Village, won the race, and saved the mountain roads.
