In the early years of the Republic of China, Nianxifang, a century-old Shaoxing wine workshop, is on the verge of collapse. Wang Yanlin, a live-in son-in-law, is framed by his brother-in-law and powerful business interests, then thrown into a wine vat and left on the brink of death. Fortunately, the Wine God of Jianhu Lake grants him a miraculous ancient book on yellow rice wine brewing, setting him on a path to protect China's winemaking heritage. Faced with schemes to steal his recipes and poison his wine vats, he repeatedly overcomes crises with traditional brewing techniques. He humiliates his powerful rivals in wine-tasting competitions, saves the workshop from ruin, secures a major military supply contract, and collects all seven wine talismans. In the end, he discovers the true essence of winemaking, restores Nianxifang to its former glory, and spreads the spirit of yellow rice wine far and wide.
