Tris and Tobias, together with a group of friends, go outside their home. They want to know the truth and gain freedom. But they end up straight in... the Bureau of Genetic Protection.

It turns out that a genetic War for Purity flared up in the past. As a result, the world was divided into “genetically pure” and “genetically damaged” individuals. And scientists turned into possessed monsters and began experimenting: creating artificial settlements and introducing their agents into them. The main goal of the experimental subjects is to serve as consumables and produce “genetically pure” offspring.

Tris is outraged to the core, Tobias rushes about in search of himself and gets into yet another mess. And the scientists from the Bureau are again unhappy. They intend to arrange a “reboot”, that is, erase the memory of all residents of the city. Tris decides to prevent a disaster!.. Who will win?
