The story begins with three young ladies (Anamika Chakraborty as Sofia and her two friends, Uma and Joyi) attend a party together with all of them hooking with different partners.

Kolkata Police detective Shabor Dasgupta (Saswata Chatterjee) is entrusted with the daunting task of solving the mystery when suddenly another similar murder occurred in Chandannagar.

Under orders from DIG Rajat Gupta, ACP Shabor Dasgupta (Saswata Chatterjee), Detective Department, Lalbajar, Kolkata Police along with his assistants Senior Inspector Nandalal Roy(Subhrajeet Dutta) and Senior Inspector Sanjib Das (Gaurav Chakraborty) travel to Chandannager to investigate the possible serial killer who murdered Rinku Roy (Diti Saha) and Sofia(Anamika Chakraborty) and the other two.

Shabor questions Sumana (Arunima Ghosh) about her husband Bijoy Sen. On the other hand, Nandu goes on a date with one of Sopia's friend Uma (Tuhina Das).

Next day Nandu gets a sudden call from Uma while he was on the street with ACP Shabor and Sanjib saying that she was being attacked by someone named Bijoy Sen and just when she was about to say her location she is stopped and killed in a similar way like the previous two cases.

ACP Shabor Dasgupta explains how the negligence of parents about their kids and how pursuing their own interests in turn leaves the child vulnerable and alone in their vital period of childhood.
