Velan, a young boy, lives with his mother, younger half-brother Balan, and stepfather Subbaiah Pillai, whom he despises. Fifteen years later, Boxer Daniel, a corrupt politician, attempts to bribe the residents of 14 villages to win the by-election. When Daniel's goons try to distribute the money, Velan, now a police officer named Osthe Velan, confronts them and seizes the funds. Velan still harbours hatred towards his stepfamily. Balan falls in love with Nirmala, but his father disapproves due to a loan he took to start an oil mill, which he can only repay if Balan marries a wealthy woman.
Meanwhile, Daniel becomes enraged when he learns the money has not been distributed and attempts to contact his goons. The goons mistakenly go to the Kattupakkam Police Station while searching for Velan's house, leading to a chase between them and the police team. During the pursuit, Velan falls in love with Neduvalli, whose father is a drunkard. Daniel tries to retrieve the money with the collector's support, but Velan refuses to return it and mocks him instead. Daniel confronts Velan at the check post, but Velan displays his attitude, irritating Daniel. Daniel hires a contract killer to eliminate Velan.
Balan steals the money from Velan to marry Nirmala and gives it to her father, who accepts their marriage. Velan asks for Neduvalli's hand in marriage, but she declines, citing her need to care for her ailing father. Upon returning home, Velan discovers his mother's lifeless body. At her funeral, he unsuccessfully urges his stepfather and brother to reconcile. A fight ensues between the contract killer's goons and Velan at the railway station, resulting in the contract killer's death. Velan deceives the Police Commissioner, claiming the contract killer was hiding to assassinate Daniel.
Daniel devises a plan to make Velan his bodyguard, but it fails. Velan asks Neduvalli's father to allow him to marry her, and he agrees, sacrificing himself since his daughter would not accept while he was alive. Velan then takes Neduvalli to Balan's wedding, interrupts the ceremony, and marries Neduvalli instead. Subbaiah Pillai is now ashamed of him, but Velan confronts him aggressively. Daniel requests Minister Kalaipandian to suspend Velan, but Kalaipandian requires a valid reason. Balan assaults an employee due to a small mishap at his father's factory, leading to Velan beating up Balan. The people of Kattupakam demand Velan's suspension, prompting him to apologise to Balan.
Kalaipandian informs Velan of his suspension, but Velan aligns himself with Kalaipandian, leading to the revocation of the suspension order. Velan poisons Daniel's adulterated alcohol and raids the location where Daniel is present, confiscating the additional money. In retaliation, Daniel sets fire to Subbaiah Pillai's factory, resulting in a heart attack. Needing to pay for his father's operation, Balan becomes Daniel's henchman and is told to give a fruit basket to Kalaipandian at his house. Unknown to Balan, Daniel has placed a bomb inside the basket, which explodes after Balan leaves, killing Kalaipandian and Constable Masanamoorthy.
Daniel instructs Balan to kill Velan, but Balan refuses, and Velan fakes his death. The next day, Velan visits Subbaiah Pillai in the hospital and pays for his operation. Daniel praises Balan but reveals that he murdered Velan's mother, takes Balan hostage, and engages in a fight with Velan. Velan rescues Balan and both suffocate Daniel to death with the exhaust pipe of a tractor. Balan later marries Nirmala.
