Aravindan Sivasamy (Jayam Ravi) is a 26-year-old youth who was brought up in an ashram run by Harichandra (Nassar). The atmosphere that he grew taught him high moral values, disciplines, dignity, devotion, etc. However, when he comes out of the place, his belief and learning is questioned by the cancerous system. It unsettles him and makes him fight against the immoral cultures of the society. Aravindan decides to take on corrupt bureaucrats. His friend Ramachandran (Soori), a lawyer named Raja Sendhoorapandian (Subbu Panchu), a journalist named Gopinath (C. Gopinath), along with his girlfriend Poomaari Mariappan (Amala Paul), join him in his mission to fight against the corruption.

They form a plan and successfully expose 147 government officials, including a court judge and MP, and are caught taking bribes for an unknown person by the name of Hari Chandran, which was created by Aravindhan using his own picture but modified to look different. All of the corrupted officials team up to take on Aravindan and his team with a look-alike, who fits the image and description of Hari named Narasimha Reddy (Jayam Ravi), a 42-year-old middle-aged man who does underground work for the Andhra Pradesh government with hints of him being a womanizer; to showcase that Hari is indeed a real person, as a method of thwarting Aravindan's battle.

Narasimha, who resides in Andhra Pradesh, accepts the deal with the government officials with the condition of the corrupt officials giving him 14.7 crores to seal the deal. Fearing that all his efforts will go in vain, Aravindan heads to Andhra Pradesh to thwart Narasimha from claiming the false identity of Hari, leading to a fight between the two. As the case takes place in court, Aravindan and his team members are dejected due to Narasimha claiming himself as Hari.

When the corrupt officials are happy that things are going as planned, the plot twist occurs where Narasimha states the truth, indicating that he was supporting Aravindan from the start after all. The court declares in favor of Aravindan, and Narasimha praises Aravindan for his effort. Narasimha further explains who exactly he is, as he is a person who runs orphanages and senior homes for female children and elders. He explains that he used the 14.7 crores to build orphanages in four separate states.

As Aravindan and Narasimha embrace each other and step out of the court, Narasimha is stabbed multiple times, and a fight breaks out, as the henchmen are set up by the corrupt officials to kill Aravindan and Narasimha. Aravindan and Narasimha, with the help of the public, fight the battle, where Narasimha saves Aravindan from being stabbed. Narasimha dies to his injuries from further wounds, leaving Aravindan and his team devastated. The end credits showcase that Aravindan and his team become successful in their problems fight against corruption.
