Sixteen years have passed since Rakesh Trivedi (Saif Ali Khan) and his wife Vimmi Saluja Trivedi (Rani Mukerji) retired from conning others with the brand "Bunty Aur Babli" for money, having been let go by DCP Dashrath Singh. A businessman named Chaddha (Neeraj Sood), as well as his rich affiliates, decide to invest money in a "party nation" by Chaddha's assistant and his friend. However, it soon turns out that Chaddha and his associates have been conned, and the culprits, revealed to be Kunal Singh (Siddhant Chaturvedi) and Sonia Rawat (Sharvari Wagh), decide to take on the pseudonym "Bunty Aur Babli", having heard stories of the original "Bunty Aur Babli" who were never caught, assuming that they would be able to escape from the clutches of the law, too.
