Rakesh Trivedi (Abhishek Bachchan) is from a small village named Fursatganj. His father is a ticket collector on a train and wants him to get into a similar occupation as well. However, Rakesh has big dreams; he is forever coming up with new business schemes and is convinced he will make it big one day. He adamantly refuses any notion that he will one day work in a 9-to-5 environment.Vimmi Saluja (Rani Mukerji) is the daughter of a Punjabi family in another small village named Pankinagar; she spends her hours watching films and studying supermodels and dreams of becoming Miss India.Vimmi’s parents tell her they have arranged her marriage to a young man with a decent job. At the same time, Rakesh’s father gives him an ultimatum – go on the job interview he has arranged or get out of the house.
Rakesh and Vimmi pack their bags and sneak out in the dark of night. They bump into each other at a train station and become friends after realising their stories are similar. They support and encourage each other to achieve their dreams: Vimmi tries to enter the Miss India contest but gets thrown out after an argument. Rakesh tries to sell his ideas for an investment scheme, but a businessman turns him away. In fact, a man he had met at a restaurant stole ideas from Rakesh’s presentation file and, when he enters the office, the interviewer states someone before he came in with the same idea. After finding out that the businessman who Rakesh had approached, used his idea to make money, he and Vimmi con him and take the money they believe is rightfully theirs.
Once they realise how easy it is to con people, they decide to run some more cons to raise money to make it to Bombay.Unfortunately, they find the lifestyle too exciting to give up. Adopting the names of ‘Bunty’ and ‘Babli’, they successfully pull off con after con, looting the rich dressed as local guides, religious priests, health inspectors, business partners, etc. Their flamboyant antics make them famous in newspapers nationwide. Soon their friendship leads to romance and they decide to continue conning as husband and wife.
