Five years since her terrifying experience in the mysterious hills and Rahul's death as a fallout, Shivangi (Parno Mitra) has settled back at home in Kolkata, living with her little daughter and aged father. She works for a media network company as a senior researcher and investigative journalist for the crime segment. It's a quiet life and she is content with it. Tragedy strikes out of the blue on the day after Shivangi's daughter's fifth birthday celebration, in the form of the murder of one of Shivangi's closest friends and admirer. Kolkata Police arrests a student from the deceased's music school as she was last seen entering the dead man's flat, but she unfortunately has no recollection of the event.
Distraught Shivangi starts her investigation in parallel, but is further jolted by a similar murder of her colleague at the media office, whilst his fiancee is arrested by the police. Strangely, even she has no recollection of the events at the time of his murder. Matters take a turn for the worse when Shivangi's house help dies under similar circumstances at the former's residence and this time, the issue seems to be getting terribly personal - the alleged murderer is the deceased's fiance, last seen on camera entering the premises but even he has no recollection of his actions. Shivangi feels the presence of a clown around her, but can't prove it to the police. She realizes that the fear is gripping closer to her and her daughter is somehow involved with each murder.
Chupkotha 2 is loaded with intrigue from the beginning until the end. Due to the involvement of the little girl with each murder, it's difficult to remain detached or indifferent to the proceedings. Director Rick Basu wastes no time with distractions and goes about the business of unleashing the series of murders quite methodically, slowly adding characters to the script without crowding the space too much. But Chupkotha 2 may have been more terrifying, the director for some unknown reason has stayed away from displaying the fear factor during each murder, only showing up the dead bodies afterwards. It's an opportunity lost in lifting the production value to the core genre of horror. Parno Mitra stands out in the central role, and the series has ace cinematography by Basudeb Chakraborty and haunting music by Diptarka Bose, which give Chupkotha 2 a mysterious shroud.
