In 1995, Ashwat Raina, an IAS officer from the Research and Analysis Wing, suggests the ministers perform a retaliatory nuclear test in response to the recent nuclear missile tests by China. However, he is ridiculed, and the PMO secretary Suresh Yadav tells him to keep the file of his plan brief. Ashwat submits the file along with a floppy containing the details, but Yadav submits a half-baked plan to the Prime Minister and ignores the floppy. The test is hastily conducted without Ashwat's involvement, who then becomes the scapegoat when an American Lacrosse Satellite photographs the test preparations, and the United States warns India not to continue with the tests. Ashwat loses his job, and three years later, in 1998, when a new Prime Minister is sworn in, he is approached by the new PMO secretary Himanshu Shukla who questions the failure of the tests. Ashwat explains the most integral part of the mission was to keep it confidential, but it couldn't happen since no one viewed the floppy. Himanshu gives Ashwat a second chance to conduct the tests, for which he starts preparing a team. Selecting five members from the BARC (Bhabha Atomic Research Centre), DRDO (Defence Research and Development Organisation), Indian Army, ISA (Indian Space Agency) and IB (Intelligence Bureau (India)), Ashwat leads the team to Pokhran for the test setup.
