Twenty-year-old vagabond Damir returns to Alma-Ata to restore his documents and start a normal life. In the meantime, he chooses a free apartment in the very center of the city - the roof of a multi-story building. It soon turns out that a teenager with autism, Kostik, who runs away from an apartment in the building and calls himself "Agent Koklinch", also considers the roof his own. While they fight for territory, Kostik regains his lost speech, and his family clings to Damir as if he were a miracle worker. But Damir has enough of his own problems, but everything changes with the appearance of Sofia, a student of Kostik's mother. In pursuit of the girl's heart, Damir throws himself into an adventure that makes him reconsider his ideas about normality.
