Delivery rider Lin Zhou is in debt. One night at 23:00, he received a strange red order - to deliver a bowl of wontons to the scene of a car accident. The recipient was a ghost. The delivery fee is 500 yuan, and the positive reviews say "the soup is a bit salty." From then on, he was bound to the "yin and yang delivery system", delivering meals during the day and ghosts during the hours, and had to abide by more than thirty death rules. What's even more bizarre is that his father, who has been missing for fifteen years, was also an ace rider in this industry.
