Programmer Qi Yuan received a mysterious express delivery from his late mother, which contained an old-fashioned mobile phone that could not be turned on normally and a note with strange rules written on it.
The mobile phone automatically turns on at midnight and displays the first rule information. At the same time, phenomena that do not conform to the laws of physics begin to appear in the apartment, implying that normal cognition is being distorted.
The mysterious woman Su Yuqing suddenly visits and warns Qi Yuan not to believe in any "red mark" rules, implying that she knows more about the inside story of "cognitive pollution".
Qi Yuan discovered that the apartment manager and some neighbors behaved abnormally, his own memory was confused, and fatal conflicts between the rules of mobile phones and reality began to arise.
