In 1998, Shiva is a happy-go-lucky police constable, who along with his girlfriend Revathi, a driving instructor, decide to elope and get married. However, Shiva gets involved in a road rage case and arrests Rajasekhar alias "Raju", a dreaded gangster who does dirty jobs for CM Dakshayani and her party. George, who is imprisoned by Shiva, tells him that he is a CBI officer who has to produce Raju in court situated at Bangalore in 48 hours, as Raju has useful information regarding Dakshayani's involvement in a orchestrated bomb blast at Morampudi in order to overthrow a state government run by a regional party. Shiva calls Varghese and confirms the same. It is later revealed that Shiva's elder brother, Vishnu, was one of the victims of the Morampudi bomb blast as he was rescuing innocent bystanders. Shiva had later joined the force in order to fulfill his brother's dream of becoming a sub-inspector (SI).Meanwhile, chief minister Dakshayani learns of Raju's arrest and assigns some goons and IG Nataraj to kill him. Nataraj and Dakshyini's goons try to kill Raju and George, but Shiva subdues the goons and escapes with them. Shiva, Raju and George head to Bangalore, where Revathi also accompanies them. Nataraj tracks them down where their car fell into a lake near a dam. Shiva, Raju, Revathi and George sneak into the dam's underground tunnel, where Nataraj attacks them and George is killed in a crossfire. After escaping from Nataraj, Shiva, Revathi and Raju go to the hospital, as Raju was injured during the previous shootout, but the hospital is watched by Nataraj's men.Later, the trio arrive at Maj. Gen. Philips Satya Raj and Raju gets operated. After this, the trio are escorted by officers under Varghese's orders, but Nataraj and his goons surround them. Shiva and Raju fight the men, and Philips also arrives and helps Shiva and the others to escape. Due to sudden circumstances in which the trio run into Revathi's family, Raju escapes and arrives at a fair, but Shiva manages to find him. Nataraj arrives and tells Shiva to kill Raju in exchange for his father's life. However, Shiva's father tells Shiva to leave and get justice for Vishnu. He then shoots himself, killing him. Shiva escapes again with Raju and Revathi. At the railway station, the trio are attacked by Raju's brother Ravi, who was bribed by Dakshayani to kill him in exchange for taking Raju's place. A fight ensues where Raju kills Ravi.Shiva, Revathi and Raju board the train to Bangalore. Nataraj and his men follow them. A fight ensues where Raju separates from the compartment in order to save Shiva. Nataraj kills Raju, thus leaving Shiva devastated. The next day at the court, it is revealed that Shiva actually recorded Raju's confession about Dakshayani's involvement in the bomb blast, and shows the evidence in the court. Raju also confessed that Dakshayani had murdered an IAS officer who was investigating her and used the bomb blast to cover up his death. Raju tells that he did all this for Dakshayani because he had a crush on her, as he told to Revathi earlier. Dakshayani, Nataraj and other officers involved are arrested.
