Zhou Hao, an internet-famous night-market vendor in an urban village, uses livestreams advertising cheap ¥9.9 barbecue skewers to deliberately smear Sun Defa, an honest stall owner who has been in business for ten years, stealing all his customers. The elderly couple have painstakingly saved money through selling honest, quality barbecue, hoping to pay for surgery for their paralyzed son, while silently enduring public criticism. In reality, Zhou Hao uses inferior synthetic meat and even plans to exploit the boy's illness for online traffic. After several customers become unwell from eating his food, a top internet celebrity who had been deceived by him accidentally discovers the truth. Arriving at the night market, the celebrity publicly exposes Zhou Hao's fraud, fabricated claims, and scheme to frame his competitor. Ultimately, Zhou Hao faces the consequences, Sun Defa receives support from the night market authorities, and his stall regains the customers' trust. His son's surgery is successful, and he recovers.
