In 1993, during a gang war (in which police and politics got involved) three heinous killings were committed by Khoka (Rwitobroto Mukherjee), a 15-years-old drug-addicted gang leader in Chinatown, (Kolkata). These victims were as follows:
· Rumi, a member of a rival gang head by a certain Afroz (later died in prison) – he was struck by a knife through the lower abdomen and then ordered his gang member Kalu to use it to carve his name on the man’s forehead.
· An unknown police informer- his throat was silted right through with a razor at tannery by Kalu and then used it to carve his name on the man’s forehead.
· Police officer Pritam Chowdhury- he was hacked to death with a knife and then Kalu used the weapon to carve his name on the man’s forehead.
He was captured by Inspector Pranab Roy Chowdhury (Babul Supriyo), elder brother of Prabir Roy Chowdhury (Prosenjit Chatterjee). The story goes forward in 2019 where DCDD Abhijit Pakrashi (Parambrata Chatterjee), who is being regularly haunted by the last scene of Baishe Srabon is given a case by Police Commissioner Dibakar Bose to capture Khoka (Anirban Bhattacharya) who is now out of prison one month ago and committed a murder of a gang rival leader Haroo in the exactly same pattern same plot as he did in 1993. Abhijit is himself having a torrid time with his wife (Raima Sen) as he is suspecting his wife is having an affair with his journalist colleague, Surya Sinha (Abir Chatterjee). Abhijit meanwhile starts the investigation with fellow officer Rajat Chakraborty (Gaurav Chakrabarty). From old news video footage from the news channel TV Bangala Abhijit finds a person named Gora (now he calls himself Jimmy and runs a restaurant at Chinatown) present in all previous murder spots and he confronts him during which he denied of having connection or memory regarding Khoka.
