Set in the milieu of an urban middle class family, the quirky comedy deals with two brothers - Luv Agnihotri (Ali Zafar) and Kush Agnihotri (Imran Khan). While Kush works as an assistant director in the film industry, his elder brother Luv works as an investment banker in London. A casanova by heart, Luv realises he wants to get married and settle down with an Indian girl.
So Kush is given the task of bride hunting for his brother and during this quest, he encounters some wacky and funny situations. Finally, he meets Dimple Dixit (Katrina), who likes to lead a life with no boundaries. She is also from London, but is a true Indian at heart.
Dimple is the craziest girl Kush has ever met. So, while everything is finalised and preparations are in full swing, Kush realises he has fallen in love with his brother's 'dulhan'. Then follows a string of comical and unpredictable events that promise to leave audiences in splits.
