BUNTY AUR BABLI 2 is the story of two pairs of conmen. 15 years after the events of the first film, Rakesh (Saif Ali Khan) and Vimmi (Rani Mukerji) are now settled in Phursatganj. They have a son, Pappu, and have completely left the con job.
One day, Inspector Jatayu Singh (Pankaj Tripathi) arrests them for conning a group of middle aged men. They were promised a trip to a country called Virgin Island and each person in the group had paid Rs. 5 lakhs to a couple - Kunal Singh (Siddhant Chaturvedi) and Sonia Rawat (Sharvari). When these men reached the airport, they realised that hadÂ been conned. These angry men barge into the office of Kunal and Sonia only to find the logo of Bunty and Babli. Jatayu was a junior cop in the team of Dashrath Singh (Amitabh Bachchan) who was in charge of solving the Bunty and Babli case.
Hence, he knew about their whereabouts and nabbed them. Rakesh and Vimmi insist that they are innocent. But Jatayu refuses to believe them. He realises his mistake when Kunal and Sonia carry out another con job while Rakesh and Vimmi are in custody. This time, they fool a mayor (Yashpal Sharma) of a town in western Uttar Pradesh under the pretext of selling the lease of the Ganga river. Jatayu makes an offer to Rakesh and Vimmi. He asks for their help in nabbing the new Bunty and Babli. Rakesh and Vimmi agree as they are hurt that someone is using their brand which they created with lot of hard work. What happens next forms the rest of the film.
