Jiang Zhaoyue, the chief of Qingluo Stronghold, leads people to block a carriage halfway to demand payment for overdue mountain goods. However, by a twist of fate, she mistakenly kidnaps Xie Huaichuan, a scholar on his way to the capital for the imperial examinations. Coinciding with a mountain road cave-in, Xie Huaichuan is forced to stay at the stronghold and, relying on his exceptional accounting skills, helps sort out years of chaotic legacy accounts. In the process of investigating old cases and tracing the truth behind merchant Zhao Liang's embezzlement, the two bicker daily, come to know each other, and quietly develop romantic feelings. When Xie Huaichuan passes the imperial examinations, he gives up his future in the capital and returns to the mountain. A ludicrous and comical mistaken kidnapping ultimately turns into a two-way destined romance, and the two join hands to run the mountain goods business.
