A serial killer is targetting the literary greats of Kolkata. Private 'defective' Gourab Sen, aka Gora, has a reputation as a serial killer specialist. No wonder it falls upon the eccentric detective to unmask the killer!
As Gora investigates the children's death, Sonali's in-laws try to get in his way. Gora faces a complex situation when he tries to tie the events together.
Sonali's in-laws become prime suspects after Gora becomes aware of some gruesome facts. Meanwhile, the hospital death case gets increasingly complicated.
When Sreeja unearths some facts about the hospital's dead nurses and ward boys, Gora's ticking mind grows doubtful over the shoes of the deceased people in the hospital.
As Gora starts questioning the hospital staff, Sarathi appears at Sonali's in-laws' house, looking for her phone. Gora finds a silver lining when Shreyasi brings little Bonbon home.
Bonbon's enigmatic appearance and puzzling riddles make Gora deeply suspicious of a mysterious nurse who could have been involved in both criminal cases.
When Sonali's in-laws come to Gora to shed light on the nature of the mysterious nurse, the suspicion becomes more glaring. But no one realizes that the killer is in front of everyone.
