Past: Three men orchestrated a deadly bus accident, killing all passengers before looting their money and jewellery. They also attack a police van and push it to fall off a cliff. A woman escapes, takes a bus, and works in a village for her son. The boy kills a pimp when she tries to kill a man. He then takes the boy under his protection.
Present: Rathnam is a henchman who works for
MLA Panneer Selvam in
Vellore. Paneer informs him that a rogue ward councillor attempted to sexually assault a girl, so she jumps out, injuring herself. Rathnam beats up the councillor's men and hacks him to death with a chainsaw. One day, he protects Malliga, a medical student and a lookalike of his late mother Loganayagi, from the relentless pursuit of
land grabber Beema Rayudu and his brothers Subba Rayudu and Raghava Rayudu. The three brothers wanted Malliga's family to sell their land, but the family refused, which led them to attack Malliga. Rathnam protects Malliga with the help of Panneer Selvam and also reveals that she resembles Loganayagi. Malliga, on Rathnam's advice, sells the land to build a medical college. Rathnam kills Subba Rayudu and warns Beema Rayudu that he will finish him and Raghava Rayudu. When confronted by Panneer Selvam, Rathnam reveals that he met his real family and learns of his mother's past and that Beema Rayudu, Subba Rayudu, and Raghava Rayudu are Loganayagi's brothers Dharmalingam, Punniyakodi, and Keshavan. Rathnam reveals what happened.
Past: The trio (which was the three men at the start) had committed robberies, and Loganayagi had learnt about this, where she tried to stop them, but they escaped. Rathnam's father was a cop assigned to investigate the case, who learnt about this and decided to take action. The trio, to escape punishment, killed Rathnam's father, but Loganayagi survived and escaped. Loganayagi gave birth to Rathnam, but she committed suicide after she was later blamed as a prostitute by a pimp. Rathnam had killed the pimp when she tried to attack Panneer Selvam earlier.
Present: Rathnam introduces Malliga to his family. Beema Rayudu learns about this and attacks Rathnam's family, where some of Rathnam's family members are killed. Rathnam tracks Beema Rayudu and brutally kills Raghava Rayudu. He later
beheads Beema Rayudu and surrenders to the police. Before leaving for prison, Rathnam requests that Malliga marry someone and also name her child after him, but Malliga cries and hugs Rathnam. == Cast ==
