Young winemaker Chen Xiaoguo accidentally unearths ancient Ming Dynasty Wuliang cellar mud and hopes to recreate the traditional brewing method for authentic original liquor. However, it attracts the greed of liquor industry tycoon Qian Wanjin. To seize the cellar mud and the recipe, Qian Wanjin maliciously suppresses Xiaoguo's business, cuts off his supplies, and imposes a blockade, while also turning Xiaoguo's senior fellow apprentice, Zhang Yuhao, against him. Cornered with no way out, Xiaoguo uses bitter buckwheat to brew an unparalleled liquor, only to be framed. In the end, the truth comes to light: his senior fellow apprentice was actually an undercover agent. The two join forces to crush the capitalist conspiracy, preserve the craftsmanship of traditional brewing, and usher in a new chapter in liquor production.
