Khoka (Anirban Bhattacharya) commits three serial heinous killings at the age of 15 and gets captured. However, thriller and crime follow when this serial killer is out of prison after 40 years and commits another murder. The same pattern and plot are being used all over again after 40 years and Inspector Abhijit Pakrashi (Parambrata Chatterjee) has been made the in-charge for this case. Directed by Srijit Mukherji, the movie also stars talented actors like Raima Sen and Abir Chatterjee.
The film is based on the 2019 murder and its relation to the 1993 series murder. In 1993, serial killings were committed in Chinatown by Khoka. They were captured by the inspector Prabir Roy Chowdhury. The pattern of crime was repeated in 2019. While going through the file it was realized that the same men were spotted in all murder that took place in 1993. Is he one or someone else repeating the killing?
