Rudhran, an IT professional, lives a happy life with his parents Devaraj and Indhira in Chennai. He falls in love with Ananya, a lab technician, who later reciprocates his feelings. Devaraj, a transport agency owner, helps his friend Das get a loan of 6 crore from moneylender Ethiraj. However, Das cheats Devaraj by absconding with the loan, and Devaraj dies upon learning this. After Rudhran and Ananya get married, Rudhran leaves for London to settle the financial issues. Ananya becomes pregnant and gives birth to a daughter, Anya. Ananya and Anya spend time with Rudhran in London. Rudhran tells her to see his mother, and Ananya goes back to Chennai.
One day, Rudhran hears about Indhira's sudden death and Ananya's disappearance, and he travels to Chennai and carries out Indhira's funeral rites. Rudhran and Shakthi investigate Ananya's disappearance, where they meet a cab driver who had picked Ananya up from the airport. However, the driver gets killed by a motorcycle gang. Rudhran captures one of the gang members and arrives at his hideout, where he sees Varadha, whom he met at Indira's funeral. Varadha is the leader of the motorcycle gang. Rudhran tortures Varadha to reveal the truth.
Past: In 2007, Varadha and Bhoomi were recidivists in Pollachi. Pandian bailed them out and informed them of a criminally ingenious idea. A group took fingerprints of parents whose children had gone abroad and usurped their properties and land. Bhoomi worked with Subbiah, a wealthy landlord whose son is in America. Eventually, Pandian, Varadha and Bhoomi injected Subbiah, leading to his death from a heart attack. Pandian then strangled Subbiah's son, killing him, and then Pandian usurped his property and got crores of money. One night, as Pandian, Bhoomi, and Varadha celebrated, Bhoomi murdered Pandian because he wanted Subbiah's property for his own sake. Bhoomi then bribed the inspector who investigated their murders and developed his syndicate network. Bhoomi's gang targeted and injected older parents whose children travelled abroad.
After a 100-crore business deal, he targeted Rudhran's mother. After Shakthi and his wife Deepika left, Varadha and his gang entered Indhira's house and eventually killed her.
Present: Rudhran becomes furious after learning this and impales Varadha. However, Bhoomi arrives with his men and attacks Shakthi and Rudhran, where Guna, Bhoomi's henchman, hangs Shakthi to death. Bhoomi reveals that he told Varadha and his gang to kill Ananya after she arrived at Indhira's house. Bhoomi stabs Rudhran, burns the factory, and leaves Rudhran to his death, but Constable Narasimhan saves Rudhran. Distraught over his family's death, Rudhran begins his violent crusade, where he kills Sasi at a container depot.
Rudhran later kills Guna at an under-construction building. Bhoomi realizes that Rudhran is after him and tells Ganga to hire Maari to kill Rudhran. Maari attacks Rudhran and Anya at a festival in Tirukalukundram, but Rudhran kills Maari and his men. Rudhran and Bhoomi confront each other at the Kala Bairavaa temple. Rudhran kills Bhoomi's men, including Ganga, and an intense fight ensues between Bhoomi and Rudhran. Rudhran finally kills Bhoomi by injecting the same serum, which Bhoomi used to kill the parents, thus avenging his family's death.
A few years later, Rudhran runs a charitable trust under Indhira's name, where he tracks down Das in Madurai and thrashes him to avenge Devaraj's death, indicating a sequel.
