Yashovardhan Raichand (Amitabh Bachchan) and his wife Nandini (Jaya Bachchan) have raised their sons Rahul (Shah Rukh Khan) and Rohan (Hrithik Roshan) showering them with love and affection. Yash has tried to pass on to his sons the values, the heritage and the rich traditions of his family.
Nandini on the other hand has different dreams and aspirations for her sons. Her own dreams of love which she would like her sons to experience. Both her sons, but more so Rahul as she shares a special bond with him. An unusual bond that enables her to feel him even when he is not around and which will help her live through the torturous years when he leaves the house. Once that has been cultivated with love for a child that was not meant to be and who brought laughter and happiness into her empty world. A child who was adopted.
Rahul's adoption has always been kept a secret. A topic that was forbidden to be discussed in the Raichand household. But ever since Rahul himself found out at the tender age of 8 years it has been the reason for his unending devotion and gratitude for his parents - especially his father. His fatherīs every word, every wish becomes an unwritten commandment for him. From that he would never break, but unfortunately does. Because Rahul falls in love.
Rahul falls in love with Anjali (Kajol) a bubbly girl from Delhi's Chandni Chowk, who dotes on her little sister Pooja (Kareena Kapoor) and cares madly about her ailing father Bauji (Alok Nath). A simple girl whom Rahul marries and brings home. A girl whom his father will never approve off. A girl that makes a proud stubborn man forgets that he is a father and reminds a son that he is adopted.
Rahul decides to leave the mother who taught and encouraged him to fall in love and whose every waking moment henceforth will be spent waiting eagerly for her eldest son to return home. A mother whose younger son Rohan (Hrithik Roshan) makes a promise to reunite a family. Who seeks out his elder brother and tries to remind him that
It's all about loving your parents...
