After being laid off by a major tech company, Chen Mo pushes a tricycle around a technology park, selling lunchboxes for 13 yuan. His braised pork is made with generous portions of quality ingredients and simmered in a rich, deeply infused sauce, quickly earning him a loyal following. However, his success sparks the jealousy of Zhao Tianba, the owner of Ba Ge Fast Food across the street. Zhao reports him for illegally occupying public space, cuts off his exclusive sauce supply, and even uses a ten-year-old personal debt to pressure Old Wang, the seasoning supplier, into submission, relentlessly trying to destroy Chen Mo's livelihood. Cornered, Chen Mo relies on his late father's recipes and the support of his neighbors to create an entirely new signature sauce from scratch. His upgraded braised pork makes a triumphant return, sending his reputation soaring and ultimately allowing him to move his roadside stall into a proper shop.
