It follows a Nellore-based detective whose life runs into danger when he starts investigating the case of a dead body abandoned near a railway track.

He has an agency named FBI (Fatima Bureau of Investigation), and solves minor, petty cases with his assistant Sneha.

In prison that night, Athreya meets a man, Maruthi Rao, who tells him of his daughter Divya, who went missing after going to Ongole and later was found dead, clearly raped and murdered.

Athreya realizes that Maruthi Rao's information is a trap to frame him in the murder case which is related to the unidentified body found in Venkatachalam.

Meanwhile, Sneha and Vamsi find that Ajay, Harsha, and Vasudha were students who collaborated on a college project about religious crimes in India and collect their photos.

After going to Bethaballi Amman NGO's office to find it empty, Athreya deduces that Vasudha went to Rajasthan to set up their new hideout in Karni Mata Temple where the team catches her and her father and hands them over to the Nellore police.

Finally, Athreya continues his petty cases and logs heads with local police again which hints towards a sequel.
