Zheng Dajiang manages a food delivery station with more than 200 riders under his supervision. He has been a regular customer at Ma's Noodle Shop, run by Old Ma, for years. But when Zheng Dajiang asks for an extra portion of beef, Old Ma publicly humiliates him, calling him a poor delivery worker who doesn't deserve to eat meat. Having endured enough, Zheng Dajiang immediately leads all the riders from his station to the newly opened Wang's Noodle Shop across the street. Old Ma tries everything to win back customers, from lowering prices and offering discounts to maliciously reporting his competitor, but every attempt fails. In a fit of rage, he scratches Zheng Dajiang's electric scooter and is caught on surveillance footage, resulting in his detention. After eight years in business, his noodle shop closes for good. Old Ma falls ill with depression, and his wife comes to plead for forgiveness. Eventually, Old Ma realizes his mistakes and returns to his hometown to work as a farmer. Meanwhile, Zheng Dajiang earns a promotion to station manager through his sense of responsibility, standing firm in defending the dignity of every hardworking delivery rider.
