A sudden death at Kumudini Bhavan casts a shadow of mourning on everyone. As police officer Hochi arrives for investigation, he meets the eccentric Anushree.

From Janhabi to Rwik, everyone in the hostel seems to be in two minds. In the middle of the investigation, another surprising death further complicates things.

On Anushree's insistence, the police starts probing about a suspicious headphone found at one of the crime scenes. Amidst Rwik's treatment, the police suspects a person close to them.

Although the police nabs the culprit behind the subsequent murders, Durba's killer is still at large. Meanwhile, Anushree learns about Raya who had the same fate as Durba.

Investigation reveals that the deaths of Durba and Raya had a pattern. The poison found in Durba's body stuns Hochi and Anushree who are desperate to unmask the killer.

Anushree realizes the killer might be hiding in plain sight at Kumudini Bhavan. But the killer plots to kill Anushree herself to sweep everything under the rug!
