C. K. Diwakar is an Indian Revenue Service (IRS) officer in the Narcotics Control Bureau (NCB), who along with his deputy Mani, steals a narcotics shipment but gets stabbed in the process. In retaliation, Vittal Rao, a drug lord, who was due to receive the shipment, kidnaps Diwakar's son Vasu. He is willing to release Vasu if Diwakar can return to him the bag of cocaine that he stole earlier. With no other option at hand, Diwakar agrees and proceeds to Vittal's nightclub, with the bag of cocaine, where Vasu is held hostage. His act of hiding the bag in the men's toilet is noticed by NCB agent Mallika, who becomes suspicious. Thinking that Diwakar is involved in drug smuggling, she informs her superior Dhiraviyam / Mohan.
Dhiraviyam / Mohan begin to pursue Diwakar, taking away the bag of cocaine from the toilet in the process. When Diwakar realises that the bag of cocaine has gone missing, he decides to return to Vittal a bag containing packets of milk powder instead, thinking that he and his cronies, including a gangster named Pedha Babu, will not realise the difference. Unfortunately, Vittal and Pedha soon find out that Diwakar had cheated them and decide to kill him. Diwakar's wound gets worse and starts bleeding. Caught between Vittal's gang on one side and Mallika and Dhiraviyam / Mohan on the other side, Diwakar confronts Mallika and tells her that contrary to her suspicions, he has been working undercover and had planned the entire operation to expose cops such as Dhiraviyam / Mohan and Mani, who are involved in drug smuggling.
Diwakar then rescues Vasu without Vittal's knowledge, and Vittal is also arrested by Mallika and Dhiraviyam / Mohan. While taking Vittal to prison, Mallika finds out that she has Mani's mobile phone, and on reading the messages in it, she finds out that Diwakar had been speaking the truth all along, realising that Dhiraviyam / Mohan and Mani are involved in drug smuggling and had tried to frame Diwakar. Though Dhiraviyam tries to resist arrest, killing Vittal in the process, he is eventually brought to justice. Diwakar falls unconscious due to the constant bleeding of his wound and Vasu takes him to the hospital. Diwakar recovers. Three months later, Mallika is now Diwakar's deputy, and the duo is shown thwarting the attempted murder of a police officer.
