During the 1947 partition, the Lahore based family of Rajveer (Rishi Kapoor) and Amrit (Rekha) has to flee Pakistan and settle in Amritsar, Punjab. In the house that they get to stay, Amrit finds an abandoned baby boy of the Muslim family who owned the house but fled to Pakistan because of communal riots. Amrit raises the boy as her own and he grows up to be Ishaan (Luv Sinha). During a summer camp visit to Kashmir, Ishaan falls in love with Chandni (Feryna Wazheir). When he goes to her house to ask her hand in marriage, her father (Deep Dhillon) and uncle (Ahmed Khan) tell him to forget her as they are against her marrying a Sikh boy. When Amrit and Rajveer come to know about this they finally declare the truth to Ishaan that he is a Muslim in reality and not their child. He doesn't believe them and Chandni's parents refuse to believe it without proof. The old couple then decides to track Ishaan's real parents down and also succeed. Ishaan's real mother, Benazir (Hema Malini) comes down with his real father (Javed Sheikh) to take back custody of a now grown-up Ishaan. Chandni's parents immediately agree to the marriage when Ishaan's real parents visit their house. What complications arise when Ishaan's parents start making plans to take Ishaan and his bride back to Pakistan and how they are handled by the principal characters forms the rest of the plot.
