Raid is based on a true story, is about an honest income-tax officer and his most challenging raid. Amay Patnaik (Ajay Devgn) is an income-tax officer with cent per cent integrity. He doesn’t accept bribes and even refuses to accept gifts as, according to him, a gift by a member of the public to a government servant like him is akin to a bribe. Amay has just recently been posted in Lucknow and the year is 1981. He and wife Malini (Ileana D’cruz) have moved in into their modest house and have just about settled there.
One day, Amay receives a phone call from an unknown caller who informs him about black money in the local MP, Rameshwar Singh’s (Saurabh Shukla) house. Rameshwar Singh wields so much power that the people of Lucknow call him Tauji and almost worship him. Amay does his homework and, after being convinced about the tip-off that the informer has given him, raids the house of Tauji following authorisation by the D.I. Commissioner (Udayvir Singh). Amay, his team of assistants and a number of police officers reach Tauji’s mansion and, much to the shock of Tauji and his large extended family, begin the raid after completing the formalities and explaining the family members the rules to be followed by themselves (income-tax department officers) and by the family members. Tauji and his family members try their level best to browbeat Amay and drive him away by threatening him of dire consequences but Amay doesn’t budge.
After many hours of search, Amay and his team get nothing of the Rs. 420 crore of black money believed to be hidden in the house and other places. Just as it begins to appear that Amay’s mission was going to yield nothing and that Tauji would, therefore, seek revenge by ruining his career, Amay tastes some success. He then starts getting more and more lucky as he unearths more and more black money, gold bars, items of jewellery and other riches from the most unlikely places in the mansion.
The raid continues over a few days and Amay finally unearths the entire estimated amount of unaccounted wealth. Somehow, Tauji gets the feeling that it is a member of his own family who has spilled the beans and thereby aided Amay. Tauji being Tauji, he uses all the contacts at his command to stop the raid. He even offers to pay Amay huge amounts by way of bribe. When nothing works, Tauji attacks Amay’s wife, Malini. As a last resort, Tauji musters the support of the people of Lucknow, who are his blind supporters. These supporters come to Tauji’s mansion in large numbers, armed with weapons, to prevent Amay and his team from taking the seized amount of wealth to the government treasury. It is now the question of Amay’s duty versus the lives of Amay and his team mates.
What happens thereafter? Does Amay succeed in his mission? Does he survive the raid? Are his team members and he himself able to escape from the mansion? Is the seized amount deposited in the government treasury? Who was the informer? Was there a member of Tauji’s family, who had leaked information to Amay while the raid was underway?
