The mother-in-law and daughter-in-law duo, Sanaka (Aparna Sen) and Paromita (Rituparna Sengupta), despite differences in age, backgrounds and temperaments, build a strong bond.

But when Paromita's marriage to Biru breaks down, social mores prevent the women from remaining close friends.

While Paromita marries Rajeev Shrivastav and begins a new life, her mother-in-law, Sanaka, is left heartbroken and alone and eventually falls seriously ill.

When Paromita learns of her friend's deterioration, she is compelled to flout convention, and returns to nurse Sanaka on her deathbed.

The flashback ends, Paromita leaves the funeral and realizes that she and Rajeev are expecting their first child.
