A warm, fuzzy and endearing story of naive Ghanteshwar, a middle-aged unmarried guy, who dreams of getting married one day to the girl of his dreams, but his world is turned upside down when he learns a startling truth about himself.

The royal saga of deceit, conspiracy, greed and lust continues in the third installment of the series, as the Saheb and Biwi are pitted against an enemy and everyone involved is scheming ruthlessly for their own personal gain.

Vidya Bagchi (Vidya Balan) arrives in Kolkata from London to find her missing husband Arnab Bagchi. Seven months pregnant and alone in a festive city, she begins a relentless search for her husband. With nothing to rely on except fragments from her memories about him, all clues seem to reach a dead end when everyone tries to convince Vidya that her husband does not exist. She slowly realises that nothing is what it seems. In a city soaked in lies, Vidya is determined to unravel the truth about her husband - for herself and her unborn child - even at the cost of her own life.
