Delivery rider Liu Yang accidentally rescued a kidnapped wealthy daughter during a food delivery. In order to repay his kindness, the rich man gave him 100 million. But instead of squandering it, he used the money to form a "Knights" - a high-end errand service team covering the entire city. On the surface, they deliver food and buy things on behalf of others, but secretly they are engaged in top-notch information exchange and material delivery business, and have quietly become the invisible kings of this city.
