A son's frantic search for his mother. A wife's desperate search to get back her husband. A father's endless repentance for his mis-deeds. A revolt against society's empty rituals & rules. This is all what Bipasha comprises. Saradindu alias Swamiji (Chhabi Biswas) is a debauch who marries Labanya (Chhaya Devi) & makes her pregnant. Saradindu goes to England & there he falls in love with Elice. He keeps his marriage as a secret to Elice & when he returns back to India he blatantly rufuses to recognise Labanya as his spouse. He alleges that the son (Dibyendu) Labanya has given birth is not his offspring but a result of an illegitimate relation of Labanya. The gold hearted Labanya accepts all the false allegations & departs to Allahabad to stay alone. Dibyendu goes to stay with his grand mother. Saradindu's relation with Elice breaks & he realizes his mistakes & transforms into a Swamiji. Dibyendu (Uttam Kumar) becomes an engineer with an artistic bent of mind. He meets Bipasha (Suchitra Sen) a half punjabi half bengali woman & the 2 fall in love with each other. All goes right & the 2 decide to marry when hell breaks lose. Dibyendu's uncle (mother's brother) Mr. J. C. Mukherjee mails him a letter about his identity, that he is an illegitimate son of his mother & that his mother is residing at some dirty place in Allahabad. Dibyendu leaves the marriage ceremony & runs from pillar to post searching for his mother. Bipasha on the other hand, herself a prey at the hands of the communal riots post independance, runs after her love to bring him back & help him unravel the mystery of his identity. When Dibyendu sees Bipasha at Allahabad he bursts out & asks her not to associate her life with the life of a person who has fallen in an abyss. Dibyendu after not finding his mother tries to commit suicide by slitting his throat but fortunately servives. Astonishingly Dibyendu is saved in time by his long lost father Saradindu who is now a swamiji. When Saradindu comes to know Dibyendu is his son & Bipasha is his daughter in law he once again goes through a form of self renunciation & self realisation. Through the help of his barrister friend Mr. Guha(Pahari Sanyal) Saradindu writes a letter to the couple disclosing the actual truth & facts which were kept in the dark for 22 years. Dibyendu & Bipasha are shocked to know swamiji's real identity but they cant get hold of him as after writing the letter he departs forever. In the end Dibyendu & Bipasha find Labanya & the mother & son reunite.
