Bhagwati Prasad, played by Anupam Kher, is the dedicated caretaker of his late brother's extensive estate. His life takes a complicated turn as he struggles to manage mounting debts, resorting to embezzling funds to keep his financial troubles under wraps. His wife and brother-in-law, Markutey, assist him in maintaining the estate, but their efforts are overshadowed by Bhagwati's increasing desperation.
The story intensifies when Bhagwati's niece, Renu, portrayed by Neelam Kothari, arrives from the United States. She is spoiled, entitled, and insistent on having her way, demanding a speedboat to satisfy her desire for independence. As Renu begins to scrutinize the estate's recent financial transactions, she uncovers a disturbing detail: 1.5 million rupees are missing. Frustrated by this revelation, she demands an explanation from Bhagwati within two days, intensifying the tension.
In a dramatic turn of events, Renu boards her speedboat to leave, but the departure is part of a schemed accident by Bhagwati to get rid of her. Fortunately, some fishermen nearby rescue her, and she ends up in police custody. The incident leaves her with amnesia from the accident, compelling the authorities to search for her family. As months pass without success, Salman Khan, who plays Raja, seizes the opportunity to manipulate the situation to his advantage. He claims to the police that Renu is his lost wife, pointing out a distinctive mark on her lower back as proof. He then fabricates a story about their three children, who, contrary to the truth, are actually his deceased brother's sons, to convince Renu of his story.
Raja, seeking to exploit Renu’s amnesia and her vulnerability, makes her believe that she and the children share a loving family, which begins to kindle genuine feelings between them. Over time, she starts to care deeply about Raja and the three boys, and their bond blossoms into love. Meanwhile, Bhagwati is eager to claim the estate back, and legal authorities step in, issuing a court order to freeze all of the estate’s assets until Renu is either found or her body is recovered.
As the story unfolds, Bhagwati employs various methods to locate Renu. When she is finally found, she is living with Raja and his nephews, suffering from memory loss. Bhagwati's sinister plans escalate; he becomes determined to eliminate both Raja and the children to secure the estate for himself. His greed and ruthless determination are foreshadowed as he plans to kill them once he learns her true identity—especially after she regains her memories and recognizes her uncle.
The climax reaches its peak when the police arrive to confront Bhagwati, leading to his arrest along with his accomplices. Renu is devastated to learn that Raja had not disclosed the full truth about her condition but soon realizes how much she has come to love him and the children. Her feelings deepen as she understands that she cannot bear to be separated from them.
In an emotional finale, just before leaving for the United States, Renu surprises everyone by deciding to stay. She professes her love for Raja and the children, choosing to abandon her previous life overseas. The narrative concludes with the happy reunion of Raja, Renu, and the three boys who now call them parents, and they are shown living happily with their own daughter as well, symbolizing a new beginning built on love, trust, and family bonds.
