Chen Feng works at a construction site, enduring the poor-quality canteen food and the exorbitantly priced snacks at the night market every day. After a chance encounter with Lao Zhao, an honest street vendor, he feels sympathy for him, only to discover that the entire North Gate night market is monopolized and exploited by a group led by the construction contractor Brother Sun. Moved by her husband's fellow workers, Su Yue suggests setting up an affordable snack stall. The couple pool their money to refit a three-wheeled cart and prepare fresh ingredients, selling food at exceptionally low, fair prices. With their genuine cooking skills and honesty, Chen Feng and his wife win the contract to run the construction site's canteen, and the entire night market returns to affordable prices, restoring the warmth of everyday life to ordinary working people.
