A poor orphan artist Shakuntala (Suchitra) is wooed by a notorious womanizer Rajnath Samanta(Uttam), only son of a celebrated doctor and millionaire (Pahadi Sanyal). Shakuntala's parents, gave shelter to a woman and a infant male-child. After their death, this boy, Deep Kamal, took responsibility of the girl and took the role of her elder brother. He has a mixed feeling about Rajnath- he hates his millionaire and would do anything, even con-act, to deprive him of it, but as a person he likes him. Shakuntala is indifferent to be associated with him, since she feels in his life there is no 'need' of her. What would happen when the Samanta family mystery unravel and it comes out that Deepkamal is actually Dr Samanta's biological son, whose wife left with the child? The hating Deep now wants not a share of, but full property, in exchange of not opening family skeleton. Parallely runs another sub-plot of Sabita (Dipti Ray) who stays with her FIL (Jahar Ganguli) and small child (Master Shaibal) - whose husband doesn't keep any contact with her or even his father except occasional letters. Why? What went wrong between them? With a hint of tenderness growing between this deserted wife and Deep Kamal. A beautifully crafted story - repeated in a few movies later - in two parts in fact, (Dipti's story is treated as a full movie in a few) but not so poignantly - with all around excellent performance by all, even Bhanu was restrained.
