Qingya Town's commercial route connects mountain herbs with plain silk, jointly protected by Qingya Escort Agency and Yunmen Escort Agency for years. One day, Yunmen's cargo boxes are robbed, leaving a Qingya escort banner at the scene. Yunmen's young escort leader Liu Feiyun comes to demand accountability, leaving Qingya's young escort leader Shen Yanzhou unable to clear his name. Female apothecary proprietor Lin Wantang notices something fishy from the perilla stain on the banner and investigates Wind Bell Ferry with Shen Yanzhou. Veteran escort Zhao Tieshan leaks the route due to deception, feeling guilty and remorseful. The three join forces to set a trap, intercepting the fake escort team at Mingyueping to retrieve the goods. Liu Feiyun apologizes, and the two agencies sign a joint commercial agreement. Shen Yanzhou and Lin Wantang resolve the dispute with integrity, protecting the Qingya commercial route.
