Xiaomai, a delivery rider with social anxiety, unexpectedly goes viral after a video of her making a funeral-themed delivery spreads online, forcing her into a daily routine of bizarre orders. Alongside Ajie, a walking bundle of joy, Xiaowu, an intern obsessed with data, and her rival, the robot "Flash," she stirs up a storm in the delivery world. From bowing to an urn and singing "Happy Birthday" in a morgue to teaching seniors how to use delivery apps and hanging good-luck charms on AI robots, this band of hapless riders discovers that delivery boxes can carry more than just braised chicken: they can hold the warmth of an entire city. As robotic arms learn to draw reaction images and databases grow a human touch, they use harebrained schemes to take on algorithms and warm people's hearts with their crazy ideas. After all, deliveries can get cold, but life should always be enjoyed while it's hot.
