Delivered at Wrong Frequency

Night express delivery not only delivers packages, but also the lingering obsessions of the dead. Lin Mo is an ordinary night shift courier who travels late at night in the city for high subsidies. Until he received an order sent to No. 117 Huaian Road, with a strange note: "Knock three times, but don't look at the peephole." He did so. There were two clear responses from inside the door. The next day, the news broke that a serial killer was posing as a courier. Lin Mo was horrified to find that the address he delivered last night had been the site of a massacre three years ago and was no longer inhabited. What made his spine shiver even more was that his delivery record showed that seven packages had been delivered to that silent haunted house this month. From then on, his world went off the rails. Every strange order late at night points to an unknown past event, a lingering ghost: In an abandoned hospital, intern doctors are waiting for life-saving medicine; In an old-fashioned cinema, a down-and-out director longs for the release of his film; In an unoccupied apartment, an internet celebrity repeatedly records apology videos... The package he sent is a token connecting life and death, and also the key to uncovering the truth. However, when Lin Mo tried to figure out the root cause of all this, he discovered that in the seventh package he sent, his own name was written in the recipient's name column... An urban ghost story wrapped in a courier order, a suspenseful adventure in which an ordinary little man is forced to walk on the boundary between yin and yang. When the knock on the door rings in the dead silence, do you dare to open the door?
