The boy is actually a 64 year old man Buddhadev Gupta (Amitabh Bachchan). The girl is a 34 year old woman, Nina Verma(Tabu). Buddhadev Gupta is the 64 year old chef cum owner of London's top Indian restaurant. He lives with his 85 year old mother and his only friend and confidante is his 9 year old neighbour. Buddhadev Gupta is an arrogant, egoistic, pompous man with a singular passion in life cooking, a confirmed bachelor who has never been in love.
Until Nina Verma walks into his restaurant and life. Nina Verma is a beautiful, charming, Indian woman. Cool, calm, quiet, always smiling, but independent and strong willed. Two extremes in age, character and attitude meet and against all odds fall in love. They decide to get married. And, like any Indian man, Buddhadev Gupta respectfully comes to ask Nina's father, a true Gandhian, living in Delhi, for her hand.
Sweet, just one problem. Mr. Omprakash Verma, Nina's father is 58 years old 6 years younger than Buddhadev Gupta, his would be son-in-law.
