A pen that can connect the deceased opens the door between the world and "over there". Lin Xiaoxue used this pen to write a letter to her deceased mother, but what was waiting for her was the blood-red word "cold" and the call from a nightmare. Entrepreneur Chen Mo brought this pen to the market in order to reunite with his late mother, but he didn't know that he had already become the first door to "it". When three million people held this pen, and when forty-seven bizarre deaths broke out one after another, a secret agency called the "Abnormal Management Bureau" surfaced - they blocked the entrance to the hole and used memory erasure to fight infiltration, but found that once the door was opened, it could never be closed. What's even more frightening is that those who have been entangled with pens for too long will have a "roommate" living in their skulls. It is familiar with all your memories, speaks with your voice, and waits until you finally can't tell who is the master and who is the intruder. This is the confrontation between man and the supernatural, the greed and repentance of human nature, and it is also an ongoing, silent invasion.
