After working through the night to repair the production line and save the factory tens of millions in losses, Zhou Qiming is fined 3,000 yuan by Han Yueyue, a newly parachuted-in supervisor who rigidly enforces the rules, simply for drinking a sip of water in the workshop. Factory director Gao Jianjun publicly commends him, then publicly fines him, crushing the morale of the veteran employees. As one production line failure follows another, Gao Jianjun begs for help late at night but is refused. After repairing the equipment, Zhou Qiming installs surveillance cameras and captures irrefutable evidence of Han Yueyue colluding with a fake expert to implant a virus and obtain a five-million-yuan kickback. On the day of the headquarters inspection, the evidence is exposed, and Han Yueyue is taken away by the police. Gao Jianjun reforms the factory rules and awards a 100,000-yuan bonus. Zhou Qiming shares the money with his coworkers, accepts an offer from headquarters to become a technical consultant with an annual salary of 500,000 yuan, and leaves with his dignity intact.
