When she regains her senses, she remembers everything that happened 14 years ago, but is unable to recollect her life in the mental hospital. Her treating psychiatrist is ready to discharge her to the care of her husband and her family. Sharda comes home, everything is about the same, except that her son, Sagar, has grown up and is about to be engaged to Sarita Sethi, and Nima still wears a widow's garb. A few months later Sharda sees Nima clad in a colorful saree, wearing a bindiya with sindoor in her forehead, and starts suspecting that everything is not it seems to be. She then finds out that Balraj had re-married and also has a son from his second marriage named Babbu. As details come flooding into her she experiences wild paranoia, is unable to trust anyone, as no one is what they claim to be, and she feels alone, lost, helpless, and distrustful. The rest of the family hover around - waiting to see what the new outcome is to be with Sharda and her struggle to fit into a family that has not been her's for 14 years.
