The film is about a common man who decides to abolish corruption at various levels of society.

Fifteen Mandal Revenue Officers (MROs) are found missing, and the police find that fourteen of them have been released after three days, but one of them has been killed. They find some files and a tape along with the body of the dead MRO. These files carry details of why the kidnapping of the MRO had been done and the reason for the murder of one of them and have the words A.C.F. written on them. It is understood by the police that these men were the MROs who had indulged themselves in bribery and that they were in the top 15 of the list of corrupt MROs. The A.C.F. sends the tape, with the message that they shall continue the kidnap of the corrupt officers in all the departments and that the No. 1 corrupt shall be sentenced to death according to the law of the Anti Corruption Force. The A.C.F. similarly kidnaps officials from PWD and the police department and kills the top corrupt official.

There is fear among the corrupt officials. They come forward to file their returns. For a while, there were no illegal transactions done, but the corruption soon continued in the society due to the threat of the local mob signing illegal documents and accepting bribes. Meanwhile, the A.C.F. finds that it is Badrinarayana who is the real reason behind this corruption scenario. Then the kidnapping continues. The case is investigated by a group of several old senior-level officials who are very slow-moving in their progress. However, Suryam, an IPS-passed guy who is working as a constable (as unable to pay the bribe to get the officer-level job), takes up the case to get a promotion in the department and moves ahead of those officials in a short time, taking a medical leave. He investigates the case starting with the finding of the non-corrupt official in every government office, assuming that the official would have collected the information of other corrupt officers and passed it to A.C.F. He tries to figure out what is the common thing which unites them under one roof. He gradually finds out that they are alumni of National College and working for the A.C.F. under their professor and the leader of the A.C.F., Professor Tagore.

Tagore is a simple man who leads a simple life during the daytime along with his adopted kids from different cultures (one is a Muslim, one is an American, and two of the kids are Hindu, etc.). He looks like a timid character, but brave in terms of his actions, and he is loved by all his peers. Tagore once takes one of his kids to the hospital for an injury and finds that the hospital is a place full of corruption who play with the lives of people for the sake of money. Tagore decides to expose the truth and catches them red-handed by faking a dead body as a patient. The hospital, unaware of his plans, continues their treatment even though they know that the person is dead and demand lakhs of money for treatment. Tagore produces the documents and receipts related to their fake treatment and gets the hospital sealed by the government. The hospital dean is arrested, but he commits suicide. Badrinarayana, the dean's father, is enraged by this and attempts to take revenge on Tagore. He finds Tagore in the CCTV camera and is shocked as according to him he was dead several years ago.

Tagore is a happy professor who lives with his wife Nandini, who is expecting a second child and son. On a Deepavali day, when the whole apartment is celebrating the festival, the entire building collapses due to some fault in the construction of a nearby highway, and many of the residents (including Tagore's uncle, Nandini, and Tagore's son) lose their lives. Tagore rushes to the government officials, and he learns that all this was due to Badrinarayana, the owner of a construction company and builder of that highway. Tagore finds that the highway was constructed on loose soil by which the contractions caused to collapse was very well known to him. Badrinarayana and his men thrash Tagore, but Tagore escapes from them. The incidents that he faced at the office and seeing corrupt puppets in the hands of Badrinarayana, he became frustrated and he formed the A.C.F. (Anti Corruption Force) to fight against corruption. He also kidnaps Badrinarayana and keeps him under his custody.

The constable finally finds out the people working for A.C.F. are the ex-students, and the police force captures all of them. Policemen torture them to open the identity of their leader; however, they refuse to do so. Tagore, on seeing his students suffer after Badrinarayana escapes from their custody and kills them, surrenders to the Police and requests the Police to release his students. The rising support for Tagore makes the Chief Minister meet him for higher appeal. Tagore refuses to appeal as he wants to stress the concept in the minds of everyone that if we make mistakes, we will be punished, and he doesn't want to violate it as he did the crime of killing four people. Tagore gives a speech in the court explaining what a student power the country has, but corruption is what is letting it down, also revealing how he killed Badrinarayana and his brother at the gallows section in the jail. In the end, Tagore is given a normal punishment of five years and is to be released by then.
