Santu leaves home for a better future. In Kolkata he meets Nidhi during a job interview. Soon they fall for each other and decide to get married in a registry office. A series of events turns Santu's life upside down.

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.
