 Monish Rai (Ashok Kumar) comes from a wealthy family and is in love with Devayani (Suchitra Sen), who is from a poor family. Monish wants to travel abroad for higher studies, and this will be funded by his family. He fears that his family will not approve of Devayani and will refuse to fund his foreign studies if he makes known his intention to marry her. Therefore, he and Devayani agree to delay their wedding until Monish returns to India.
 Financial problem overwhelm Devayani's father not long after Monish leaves for England. He has been taking new loans to repay old loans, and most of these new loans have come from a certain Rakhal, who poses as a friend and well-wisher of Devayani's father. Rakhal is in fact a vile and dissolute man, and he has his eye on the beautiful Devayani. At a timely moment, Rakhal makes his irresistible proposal to Devayani's father. A simple and rather gullible man, Devayani's father thinks that marrying Rakhal would be a good thing for Devayani because Rakhal is a rich man and Devayani will live a comfortable life. He agrees to give his daughter in marriage to Rakhal. A horrified Devayani tells her father that she does not want to marry at all, but to live with him and take care of him in his old age. This cuts no ice at all with the father, and the wedding date is fixed. A desperate Devayani even approaches Monish's mother for financial assistance, but is refused.
 The wedding takes place. Rakhal, who is significantly older than Devayani, makes some effort to court her, but she finds him repulsive. Rakhal soon begins to find Devayani's sour and rejectionist attitude tiresome, and he returns to his drinking and gambling cronies. He also resorts to violence when he feels insulted by Devayani's attitude. Rakhal had inherited much wealth from his father, but he is a wastrel with a fondness for drink, cards and dancing girls. He splurges money on his many bad habits and the truth is that much of his money is now gone. Devayani soon becomes pregnant and gives birth to a baby girl, Suparna. Devayani's father dies just around this time, leaving her with nowhere to turn to for succour. Her husband is briefly put in jail after a drunken brawl at a brothel, and it becomes known that his money is finished. Unhappy with her marriage and her circumstances, Devayani runs away and becomes a devadasi, or temple dancer, performing for a male clientele. She is however tracked down by Rakhal, who attempts to kidnap his daughter Suparna on more than one occasion. In order to ensure separation of father and daughter, Devayani leaves Suparna in an orphanage run by Christian missionaries, making the stipulation that Suparna should not be placed for adoption, and that she will contribute for Suparna's upkeep when possible. Devayani relocates and throws herself wholeheartedly into the project of earning a living by singing and dancing for a male audience at a traditional-style kotha (song and dance performances to a male audience, with few if any instances of sex work).
 Monish returns to the city after completing his education. He has already heard of Devayani's wedding. He is unable to forget her, and he remains unmarried all his life. Once, on the street, he sees a woman who looks like Devayani and calls out to her, but she turns away and quickly sits inside a nearby taxi with no sign of recognition and drives away. Monish is told by others that the person he has seen is a Lucknow-based tawaif, Pannabai.
 Is Devayani still alive? Who is Pannabai? What happened to Suparna?
