Directed by Deepak Sareen and written by Honey Irani, the film stars Salman Khan as a womaniser and Twinkle Khanna as his first true love.

Komal agrees, on the condition that he would have to give up his playboy lifestyle and become responsible: He would have to quit smoking, drinking, and women for her to marry him.

Komal misunderstands him and tries to leave him but after knowing the truth from his grandfather that she had changed him totally, she reciprocates Sooraj's love.

One day Sooraj returns home to find a dog named Sandy, and a boy, Kabir, claiming to be his son.

Mahesh eventually reaches there, asks the child's name, and is shocked to find that he's Sooraj's son.

Sooraj goes to London for Kabir's education without informing his grandfather, and Mahesh gives an excuse that one of his friends is in a serious condition and he has gone to visit him.

One day, after carrying everything and packing for school, Kabir shows him a photograph that helps Sooraj identify the woman he had a fling with for a few months.

Komal interrupts the conversation and Kabir is infuriated and scolds her a lot, adding that he is discussing an important matter with Sooraj.

During the wedding, a boy who is dressed like Kabir claims that he's Kapil, Sooraj's other son, but it is revealed that Mahesh sent the unknown child for some reason.
