The story opens with Vijay Chopra (Anil Kapoor) returning from USA, to join his family business. The only son of the widower industrialist, Vishwanath Chopra (Anupam Kher), Vijay carries home with him the attitude of the western world, some good, like equality of man and woman in a relaxtionship and some bad, like failure to recognise marriage as an institution.

Vishwanath hopes to bring some stability into his son's life through marriage and Vijay is all the more reluctant to tie the knot. A compromise is finally struck between the father and the son with Vijay agreeing to marry, with a condition. The condition that if he is not compatible with his wife after a year of marriage, he will leave her.

Although furious with the condition, Vishwanath realises that a marriage with a condition never the less better than no marriage at all. Vishwanath feels that there is no one better suited than Megha (Kajol), his trusted and efficient secretary, who is capable of changing his son's heart within an year of the marriage. Vijay thinks otherwise and on their first anniversary, he enforces the contract. Megha leaves his house and start working, but the society brands her character less.

When Vijay realise what is happening to Megha's life he wishes to take back but she refuses. In the midst of all, Megha realises that she is pregnant. She acknowledge Vijay as the father of her child, but not as her husband any more. Whether Vijay succeeds in winning Megha's heart see 'HUM AAPKE DIL MEIN REHTE HAIN'.
