Rakesh (Abhishek Bachchan) is a man of schemes, ideas, invention and restlessness. His small town begins to feel too small for his King size plans. In another part of India crinkle nosed small town girl, Vimmi (Rani Mukerji) doesn't want to become just another young marriageable girl. In her mind she is the Miss India that the world can't get enough of. So, they decide to fly the coup.Somewhere along their individual journeys, Rakesh and Vimmi meet. And in a moment of mistaken truth, the legend of Bunty and Babli are born. We follow the duo through caper after caper, in which they are spiritual gurus; bureaucrat and secretary, gangster and moll; business partners; hen pecked husband and pregnant wife, vagabonds and caught-in-a-downpour lovers. We watch them run rings around rajahs, power brokers, shaadi bandwallahs, millionaires, investors, leaders, ministers, elephants, explorers, hoteliers, chai boys and one very very upset policeman, DCP Dashrath Singh (Amitabh Bachchan).
