The film opens with Ivan Fyodorovich celebrating his birthday modestly with his granddaughter, Katya. She is the light of his life, as he raised her after her parents (his daughter and her husband) died in a train accident.

It seems you're asking for a proper summary of the 1999 Russian film ( Voroshilovskiy Strelok ), possibly with the word "mtrjm" (meaning "translated" or "subtitled" in Arabic) indicating you want the story clearly explained.

Devastated, Ivan takes Katya to the police to report the crime. The initial officer on duty is sympathetic but powerless. When the case is assigned to the local investigator, it becomes clear the system is corrupt. The rapists' powerful fathers pressure the police and prosecutor's office. The investigators manipulate Katya during questioning, suggesting she was "asking for it" and that she had been drinking. The medical evidence is downplayed, witnesses are threatened, and the case is eventually dismissed for "lack of evidence." The three young men walk free, smirking.
