In 1990, the last surviving member of a family of landlords in Murshidabad auctions off his valuable possessions to the local villagers, for very low returns.

He is being sent a number of unnamed chits, each stating the circumstances in which the conspirators against Siraj ud-Daulah, the last independent Nawab of Bengal, died.

Soham is immediately interested in the riddle, which hints at a particular house and Warren Hastings' court case against Maharaja Nandakumar.

The second letter says something about Dinabandhu Mitra's Neel Darpan, its translation to English by Michael Madhusudan Dutt, and the arrest of Reverend James Long for publishing the same (the British Government had declared the play as seditious).

He reveals that his father, the previous owner of the shop, knew Somnath well, and was told by him to do this in front of the person who solved the second riddle.

Soham deduces that burying a ledikeni stands for the grave of Lady Canning in Barrackpore, since the sweet was specially made on the occasion of her arrival in India.

The owner delivers the next clue to them via a telephone call with his father, which hints at going to Old Mission Church, where Madhusudan Dutt was converted to Christianity.

The Father of the church gives Soham another letter, but just as he was about to tell him more about Somnath, he is shot dead, much like the gardener in Barrackpore.

In the ensuing clash, the librarian is killed and the map and the riddle stolen by Amirchand, who finalizes selling the gift to a foreign buyer for 35 crore rupees.

Back at the Singha family household, Abhiraj beats up Sakkhi's son, a drunkard, for stealing the original nose-ring, which he continuously denies.

However, Sakkhi had had enough of Ashutosh, and reveals everything to Brishti about how her father's aristocratic lifestyle led him to mortgage everything, even the house itself, to Amirchand.

Soham remembers how the last riddle hinted at Khoshbagh, the final resting place of Siraj ud-Daulah, who had renamed Kolkata to Alinagar when he had captured Fort William from the British.

It is then revealed that Somnath had carefully placed the sword upon a high voltage wire supplying electricity to the whole of Murshidabad and Berhampore, to keep it from wrong people who choose to ignore the warnings in the riddle.

[4] Roushni Sarkar from Cinestaan praised the film's story and Paran Bandopadhyay's portrayal of Sakkhi Gopal, but found the score to be too obtrusive and jarring and felt the cinematography "[failed] to create the right ambience.
