Inhabitants of the virtual world - letters, signs, numbers - daily watch the real world from the monitor screen. Adults work on the monitor, children study at school. The question mark serves in counterintelligence, which is necessary to detect illegally infiltrated viruses. His son Voprosyatka returns home after an eventful first day of school and encounters a virus on the street. So, a massive invasion of viruses into the Cyrillic lands of the virtual world has begun. The infection is well planned. While police and militias fend off hordes of viruses with limited functionality, saboteur viruses storm the main and backup processors. The saboteurs skillfully disguise themselves, but even the schoolboy Voprosyatka easily recognizes them. Viruses are doomed while the virtual world is washed by rivers of knowledge, but its inhabitants must not let their guard down. This is the reality hidden behind the screen of every computer monitor on planet Earth.
