Plot

Mrs. Binodini Roy, a renowned industrialist, wants to marry off her elder daughter Rupa to her business partner's son (Majumdar). Rupa is against the marriage and hence escapes from her house with the help of her father. On the way to her uncle's house in Narayanpur, a cabbie tries to rob her of her belongings. But she is saved by a handsome motor-mechanic named Somu. Somu takes her to her uncle's house, and it is revealed that he is one of her uncle's acquaintances. Gradually, Rupa and Somu grow close to each other. One day they have a heated argument on her modern dressing, but it is precisely after this that they realize their love for each other. They make up and even get secretly married without informing Rupa's mother. Soon, on her father's request, Rupa returns home. Her mother refuses to acknowledge her marriage; instead, she decides to marry her off to her former match. On the day of the wedding, just when Rupa had given up all hope, Somu makes a dramatic entry to take charge of his ‘sasurbari’ (in-laws’ house). But is it only his love for Rupa that has brought him here, or does Somu have a secret of his own?
