Sagar returns to his hometown Shillong after completing studies in order to take over his father Indranil’s tea estate. It is revealed that since childhood Sagar has been in love with Jhilik who is his domestic help’s daughter, but his father does not approve of this relationship due to their class difference. Instead Indranil decides to fix his son’s marriage with his business partner’s daughter Tumpa. As an addition to the two families uniting Indranil also hires Tumpa’s elder brother Suvankar as the manager of his business. As Sagar vehemently denies his father’s orders Indranil fakes illness and takes Sagar away from Shillong while Tumpa lies to Jhilik’s mother over the phone that Sagar has decided to cut off all ties with her and her daughter. Grieved and humiliated, Tumpa and her mother leave their house and go to her maternal uncle’s house who promises to find a solution to their problem. But the corrupt uncle instead goes to Indranil and makes a pact to marry off Jhilik to some other groom if the businessman paid for all the expenses of the marriage. Meanwhile Suvankar takes over as manager of the tea estate and harms the business by taking bribes and accepting substandard products. When the previous manager confronts him about it he misbehaves with him and forces him to leave the job. While Suvankar plans to completely take over the business he realises that it is almost impossible as Indranil does not completely trust him. As a final resort Suvankar hires a goon to disable the brakes in Indranil’s car to kill him in an accident. Tumpa gets to know of the plan and informs Sagar about it who then goes and saves his father. Finally, Indranil realises his mistake and happily blesses Sagar and Jhilik’s marriage. The film has become immensely famous in popular culture because of its songs and music directed by Bappi Lahiri. Apart from becoming an iconic film in later Bengali romantic cinema, the song Chirodini tumi je amar sung by Kishore Kumar and Asha Bhosle has been etched audiences’ memory forever. The film played an instrumental role in boosting Prosenjit's stardom.
