In a decaying Calcutta mansion, Titli maintains routines after her husband Shaon disappears. The arrival of Megh during Durga Puja stirs suppressed feelings and memories as grief emerges.

Mahendra Kumar Choudhuri, the middle prince of the Bhawal Estate (also known as the Bikrampur Estate), was affected by syphilis and was taken to Darjeeling for treatment along with his wife, Chandrabati Devi, brother-in-law, Satya, and a family doctor, Ashwini. He apparently died in Darjeeling and was cremated there as well. After 12 years, a Sanyasi shows up at the estate, arousing people’s curiosity and leading to a rumour that he is the lost prince of the Bikrampur Estate.
