The Chatterjee family reaches Kharapani to celebrate Palash and Urvi's engagement. Everyone is excited about their stay at Rajbari. But are the walls of the mansion hiding a centuries-old curse within them?
A broken wall in the house reveals a beautiful idol of Shwetkali. Balaram Thakur, the village priest, asks the family to worship it as Narendrapratap did. But who is Narendrapratap?
The family's beloved dog, Gogol, is found brutally murdered. The villagers insist that Pujo is completed. Urvi holds Balaram's son responsible for the dog's death.
The family remains divided over the decision to offer an animal as a sacrifice. At night, some members witness an eerie instance. Will the family's decision not to sacrifice an animal cost them dear?
The death of a family member turns the celebrations into mourning. The police and the locals believe that the goddess is taking her sacrifice by herself. But Urvi doesn't believe this.
Arunava and Urvi find an old diary belonging to the zamindar, Narendrapratap. The diary reveals the inception of the myth of Shwetkali. Does Balaram Thakur know more than he is letting on?
Urvi learns more details about Narendrapratap's life and finds similarities between the incidents that happened 150 years ago and the ones happening now. Balaram Thakur warns her of the danger looming on her family.
