The quick‑witted schoolboy Grisha is forced to move to Kazan because of his father's work. In Volgograd, he was liked by teachers and peers. At his new place, he's an outcast and a weirdo who is constantly bullied. After ending up in the hospital following another altercation, Grisha meets the psychiatrist Evgeny Zakharevich. Meanwhile, a series of robberies occurs in the city — in the homes of speculators — and the investigation is entrusted to the head of the criminal investigation department, Nikonov.
