The film focuses on an lRS officer Amay Patnaik (Ajay Devgn), who has just been transferred[9] to Lucknow as Deputy Commissioner of Income Tax, where he lives happily with his wife Malini (Ileana D’Cruz). One day, he receives an anonymous tip about black money hoarded by (Member of Parliament) Rameshwar Singh (Saurabh Shukla), the don of Sitagarh, who had evaded income tax for a long time. So, Amay and his team, after much planning, head to Sitagarh. There he and his team face opposition from Rameshwar’s very hostile family, but he holds up to his ideals and integrity. He searches every nook and cranny of the house with his team to find the black money without any success. After a few hours of searching, when all hope seems lost, he receives an anonymous letter, along with a map, revealing the location of the money in the house. Amay and his team break down the walls, ceilings, staircases and old storerooms (with the help of the map) to find assets worth crores (tens of millions)[10]. MP Rameshwar, not willing to accept defeat, goads Amay into letting him leave the house.
