Circumstances force Debjani (Suchitra Sen) to become â€˜baijiâ€™ Pannabai. When Debjani meets her former lover, barrister Manish Roy (Bikash Roy), she asks him to take her daughter, Suparna away from her. Manish becomes Suparna's guardian and brings her up as her niece to become a lawyer (Suchitra Sen again). When Debjaniâ€™s husband Rakhal traces them out and tries to blackmail her by threatening to expose Suparna's true identity, Debjani shoots him dead. When Suparna hears Debjani's story from Manish, she defends Debjani in court and wins her case.
