Parboni recounts her past to an unexpected friend. On the night of the bisarjan, things come a full circle as all the sinners are made to pay for their past misdeeds.

With Tublu dead, Monojit Halder starts interrogating the family again. As Tublu's wife reveals a name that he had uttered in his last moment, another missing piece of the puzzle comes to the fore.

Almost everyone in the Choudhury household accuses Parboni of Choton's murder. An ear-splitting howl from one of the Choudhurys pierces the silence of the house in mourning.

As the family mourns another death, Halder stuns them all by revealing the identity of the killer. Baikuntho turns pale on hearing Parboni recollect her past. Someone notices Parboni behaving mysteriously late at night.

As Halder questions everyone about the identical keys found in the stomachs of the deceased, Parboni suddenly faints. Bulu's husband reveals a dark secret of the family. Who's turn is it now to pay for the sins of the family?
