The film features Ranjit Mallick, Sandhya Roy, Prosenjit Chatterjee, Debika Mukherjee in the lead roles.

The eldest son, nicknamed Minu is also a government employee, has a happy family in the form of his loving wife Mamata & son Raju, and is extremely devoted to his parents but since he contributes the least to the family income (only 500 rupees per month), Mamata (who came from a poor household that didn't have the ability to give any dowry) constantly faces psychological abuse from her mother-in-law & is made to do all the household chores single-handedly without any assistance from others.

In spite of all the abuse she receives from Latika, Tandra & her mother-in-law, Mamata silently endures it in order to not to hurt her caring father-in-law by sowing discord in the undivided family, much to the grief of Minu.

Since the mother-in-law measures the worth of people on the basis of the money they earn, she is also equally rude towards her blind husband, whose monthly pension of 150 rupees is mostly spent on his medications.

There, the strong-willed Dipa stands up against the abusive trio (Latika, Tandra & her mother-in-law) & emerges as a strong support for Mamata & her father-in-law, creating tensions in the family.

One day, Dipa finds Mamata preparing a dish of punti fish for Latika's household, leaving behind Raju who is bedridden with fever.

Incensed at such an act of disrespect, the mother-in-law, at the instigation of Tandra, informs Tanu her version of the story, making it appear as if Dipa was abusing her elders.

But Dipa secretly arranges for money by selling all the gold ornaments of her late mother in order to prevent Minu from resigning, so that he could continue to take care of Mamata & Raju.

The story then ends with Mamata then helping Chinu (who had been defrauded by his business partner) to reconcile with his parents, thereby preventing him from being kicked out of the house.
