[1][2][3] The original working title of the film was Nayika, but the director Saikat Bhakat changed it to Mahanayika.

In January 2015, it was revealed that debutante director Saikat Bhakat had brought Rituparna Sengupta aboard her project Mahanayika to play the lead role of Rituparna Sengupta,[4][5] and even though inspired by the life of Suchitra Sen the project would not be a biopic.

But a new crisis arises when detective officer Priyabrato Roy (Indraneil Sengupta) arrives in her life to exhume the black incidents from her past.

But at the end, we realise that Priyabrato doesn't exist in reality but as her conscience that reminds her of her past relationships and how Rajat's love was unrequited by her.

By this time, she has been sufficiently panged to break relations with Mukherjee family, only to return to work and focus on her career once again.
