The time was early eighties. Amarnath Ganguly's wife Parma, son Arup, grandmother Sumita and grandson Chiku are the apparent happy family of the current owner of Shrikant Manjil in Bhavanipur. During Durga Puja, it is decided that everyone will go for a walk together, and the crowd moves in full force. In the meantime, Amarnath started receiving mysterious phone calls and everything fell apart due to the sudden death of a member of the house just before Mahalaya. Whose phone? What does he want? Is death normal? Or no one can see despite the evidence in front of the eyes? A new researcher comes forward to solve these problems. Will he be able to get out of life in Atpaur and uncover the secret of Srikant Manjil?
