On the day Shen Mo was laid off, he rented a cheap old apartment complex. On the first night after moving in, he received a text message on his mobile phone: "Don't take the elevator after ten o'clock in the evening." He didn't take it seriously. As a result, he went downstairs to buy cigarettes in the middle of the night. When the elevator door opened, a chinless woman stood inside. He found out the next day that the neighbor who sent the text message had died three days ago. From then on, the text message arrived on time at ten o'clock every night. Each one is a rule of life. He wanted to move out, but the contract was signed for one year and the deposit was non-refundable. He wanted to call the police, but they said the text message was a prank. He could only bite the bullet and live in it, while dealing with the weirdness in the building and finding out how the previous tenant died. Until he discovered that the strangeness of this building was related to the property's charging standards.
