Before the Zhou family shopkeeper's bones have even grown cold, a greedy elder uncle and a biased grandfather drive a widowed mother and her children out of the family home, leaving them with nothing but a foul-smelling, discarded fermentation crock. The whole town waits to laugh at them, but who could have guessed that Zhou An, the disgraced son cast aside by his family, would discover at the bottom of the broken crock a century-old, secret starter culture and the Book of Fermentation that his father had risked his life to preserve? Facing relentless persecution from his greedy relatives, attempts to cut off his livelihood, and malicious suppression by powerful wealthy families, watch how Zhou An uses his extraordinary ingenuity and peerless aged fermented paste to set ingenious traps and challenge his rivals at the sauce-tasting arena. Turning their own tactics against them, he makes the family's once-proud reputation a laughingstock, stages a spectacular comeback, and restores the honor of the true sauce-making lineage!
