Vibha Singh (Vibha Chibber) is a corrupt bureaucrat in the Accounts Department of the Government who pushes many of her clients into giving her “percentages” of their money which may either have been stolen or confiscated. With the support of her assistant Hamid (Pankaj Tripathi), she continues to do so and keeps hiding the money in a basement of the Rashtrapati Bhavan which is only known to her, and resumes her lifestyle until she receives news from Kirit Ojha, the Principal Secretary to the Prime Minister, that her help is needed critically by the Prime Minister for a certain task, and Ojha sends his man, Irfan(Boman Irani) to work with them and start an investigation from within their department to avoid being caught, as the investigation in question is against the notorious criminal King, who has recently stolen jewels from a jewelry house owner Mehta, and has claimed that his next target would be the Rashtrapati Bhavan. For the same, a hacker from the technical department, named Raj (Gaurav Chaudhari), is chosen to decipher messages of the gang.
