Back-kitchen chef Xu Dachuan is abandoned by his boss who runs away after withholding his salary, accidentally activating the Super Catering System. Stuck in a snow traffic jam, he sets up a street stall relying on exquisite cooking skills to sell hot food, gaining his first batch of customers and appreciation from influential figures through superb flavors. After returning home, he sets up a stall to sell secret-recipe spiced meat to show his initial edge, then rushes to the city, overcomes capital and venue difficulties, starts a business by taking orders with a heart-crafted box lunch, deeply cultivates the catering industry step by step, struggles steadily, and counter-attacks his life to break out a career with fireworks craftsmanship.
