Truck driver He Guoping dies suddenly on the road, lying alone in his cab for three days before anyone finds him. His elderly father, his wife, and his eight-year-old daughter He Xiaohe are more than 1,500 kilometers away—no one at home can drive a heavy truck, and they have no way to bring him and the vehicle back. After a plea for help goes out in a truckers' group chat, four drivers who have never met—Zhou Dajiang, Guo Haifeng, Sun Mingliang, and Du Xiaochuan—step forward despite worries about bad luck, liability, and expenses. They pay 12,000 yuan out of their own pockets for the journey, clean out He Guoping's cab, bring his ashes back, and decide to finish the final delivery he never completed before taking him home.
