The city of the future, buildings hundreds of stories high are heading upward. What happened to society? It split into classes. Now in all megacities, each floor occupies a strictly defined social stratum. The city is strictly divided into levels. Those who least deserve comfortable living conditions go down, only the most “sinless” remain at the top, a high-tech tracking system protects order and peace everywhere. In the city of the future, no one can hide from the tracking system, which is only gaining momentum these days. She “sees” everything, knows everything about each person, she leaves the right to decide who should be on which floor behind her. The main character of the book, who is part of the class of the intellectual “celestial” elite, is accused of committing a crime. Where to run? Where can you hide from the “all-seeing eye”? Fearing the System, foreseeing exile to the lower levels threatening him, our hero decides to do something unthinkable to himself.
