Chemistry teacher Li Mingzhe turns his barbecue stand into a hardcore laboratory, using scientific methods such as acid-base titration and centrifugal dehydration to precisely control the Maillard reaction. Not only does he expose the harmful sauces of inferior competitors, but he also uses chemical equations to tutor his students, filling the small stall with human warmth. However, an arrogant corporate chef attempts to buy out his recipe, and after being rejected, threatens to destroy the stall with an industrial assembly line. Facing corporate encirclement, whether this soul-filled scientific barbecue can defeat the cold machine and protect the warmth of fireworks becomes the ultimate suspense.
