In Jinmen in the 16th year of the Republic of China, Su Yanwei, a descendant of the ancient Mo family, guarded Shuyu Zhai for a century and struggled to survive with his unique skills in carving. She got acquainted with Lu Yanci, a customs anti-smuggling clerk, because of the remaining ink on her side of the "cold pond wild goose shadow". The remaining ink contains a secret message about the national treasure of the Southern Dynasties, implicating the smuggling conspiracy of foreign merchants and the secrets of the Su family's ancestors. In troubled times, craftsmen stick to their craftsmanship, and patriots hide their solitude. The two use ink as their blades to protect national treasures and their country. In the smoke of pine and ink, they compose a legend of the Republic of China intertwined with faith and affection.
