Zhou Changhe, a 63-year-old master pastry chef, is deceived by his own nephew, Zhou Yaohui, and kicked out of the family bun shop. Armed with thirty years of experience, he joins Xiangyunzhai, a century-old restaurant on the verge of bankruptcy, and brings the time-honored establishment back to life with a single basket of soup-filled buns. Facing his nephew's malicious competition and online slander, he chooses to settle the score in a livestream, letting loyal customers witness what true craftsmanship looks like. From being mocked as nothing more than a dough kneader to becoming an officially recognized inheritor of intangible cultural heritage, he protects not only his craft but also the dignity of a generation of artisans. When Yaohui Pastries goes bankrupt because of its corner-cutting, Zhou Yaohui kneels and begs his second uncle to save him. But Zhou Changhe simply says, 'A pot isn't something you remember to wipe clean only after something goes wrong.'
