Han Chuan, an auto mechanic, is owed wages by his boss, Ma Guoqiang. Instead of paying him, the boss gives him a scrapped tow truck as compensation, publicly humiliates him, and tries to destroy his career. Han Chuan records the evidence and takes on an urgent roadside rescue job that is already overdue, completing the repair with his exceptional skills. Ma Guoqiang secretly joins forces with auto parts suppliers to cut off Han Chuan's access to parts. Han Chuan turns to scrapyards to source everything he needs, builds his own parts inventory, and brings together small repair shops on the street that have also been suppressed. Together, they establish an integrated network for rescue services, parts supply, and repairs. In the end, Han Chuan secures a pilot partnership for nighttime rescue services with an insurance company, renovates the old tow truck, and opens a rescue center, revitalizing the entire auto repair street and carving out a livelihood through his own abilities.
