When two mysterious men start killing his family membersone by one, Raghupati decides to get his daughter Shruti married to an NRI named Krishna Prasad, for her safety. Contrary to the family's expectations, Krishna turns out to be a well-cultured man who respects the traditions. He wins over everyone with his nature, but Shruti doesn't want to leave her family after their marriage. Raghupati's enemies continue trying to kill his family members, and one such encounter results in a fight at the river bridge. Having learnt about the rival Veerabhadram who wants Raghupati's family died due to a misunderstanding and thus sent the goons, Krishna warns him not to mess with his family again. Shruti has a change of heart but pleads Krishna to leave behind his business and stay in the village. He readily agrees before the two attackers arrive. Shruti's brother Mahendra hands over a sword to Krishna to kill them. However, Krishna kills Mahendra and other men with the help of the killers. He also kills Shruti's uncle Ganapathi and holds her hostage. Upon being questioned by her, Krishna reveals himself to be an Indian Army Major named Sanjeev, and the killers are none other than his colleagues, Captain Amith and Captain Satyaveer. When Krishna's brother Ajay committed suicide due to lung cancer caused by chain-smoking, he decided to investigate the matter with the help of his girlfriend Geetha. Together, they found out about a heavy dose of drugs mixed in cigarettes manufactured by the Tiger brand. Sanjeev started a "Mission Oxygen" and got the brand banned after capturing and killing its owner. While returning to duty, Sanjeev learned someone was trying to find about him and his family and tried to warn Geetha. Raghupati's brothers, the real owners of the Tiger Brand and its poisonous formula, killed Sanjeev's parents. In order to prevent them from knowing about Sanjeev, Geetha leaked the gas cylinder and caused an explosion that kills her. The men survived and escaped, while Sanjeev was shattered after hearing everything on the phone. His colleagues killed Shruti's uncle who came to know Sanjeev was inquiring about the attackers. His death terrified Shruti's family members who stopped leaving home. Sanjeev sent details about the marriage to Raghupati via his dead brother's phone, and thus came as Krishna Prasad to kill his family members responsible. Shruti is now convinced and decides to help Sanjeev with retrieving the cigarette formula. They manage to retrieve the black moneylocked in a safe by Raghupati's brothers and distribute it to the affected parties. Learning from his brother about Sanjeev's truth and Shruti's kidnapping, Raghupati is shocked and admitted to the hospital. A police officer tries to catch Sanjeev after the money distribution but in vain. Sanjeev and his colleagues break into the factory to retrieve the formula while Shruti uploads the link to a live broadcast of the operation. A fight ensues, leaving Sanjeev wounded and his colleagues dead. Raghupati is then revealed to be the real creator of the cigarette who has the formula hidden in his own mind. Through the CCTV footage airing live, everyone learns about him. Sanjeev urges people to quit smoking for one last time and then proceeds to jump into the fire along with Raghupati, killing him and blasting the factory. The public is motivated to give up smoking, while the police close the case and declare Sanjeev dead. However, he is revealed to be alive in Mumbai after the police officer, who tried to catch him, assures support whenever needed.
