This is the story of a woman who loved not wisely, but too well. Nirmala (Nargis) was a coy college girl whose maidenly heart was given away in love to her classmate Rajinder (Pradeep Kumar) who separated from her when it was least expected.
Nirmala’s aunt (Chand Burque) on whose grudging and grumbling charity Nirmala and her widowed mother (Pratima Devi) were dependent for their daily bread planned to marry Nirmala to a rich but good for nothing widower for substantial pecuniary gain and riddance of a dependent at the same time.
Nirmala spurned the marriage proposal of her aunt and on the latter’s threat of refusal to maintain Nirmala and her mother she went to seek for a job and fell into a well laid trap of Kedarnath (Pran), a notorious and most unscrupulous villain. From now on her life became miserable because she could not stand against the tricks of Kedarnath due to which she was thrown out of the house and was placed at the mercy of snobbish society.
Time changed and once again spring came in the life of Nirmala when she met her lover but only for a short time. The happiness was cut short by sudden departure of Rajinder for higher studies abroad. Finding Nirmala again stranded her shadow of doom. Kedarnath again started his old villainous game till he was properly dealt with by the invisible blow of eternal justice.
What became of Nirmala the victim of circumstances can only be revealed by the SILVER SCREEN.
