Rajashekar is a strict traffic police officer whose marriage is arranged with Madhan's sister. However, Madhan, an arrogant street racer, cannot forgive Rajashekar for humiliating him in the past.

Madhan is a brash street racer who lives in a city with his loving elder sister Raji or Poonai. They were orphaned in childhood. They are living with their aunt Dhanalakshmi. He has a love interest named Kavin. Rajashekar is a stern traffic police officer. Sparks fly between them at the beginning of the film itself when Rajasekar nabs Madhan on the road for racing and humiliates him in public by putting a girl's dress on him. When a marriage alliance is formed between Raji and Rajashekar, things become tense. Madhan is not able to put the humiliation behind him and begins to see Rajasekar and Raji as his worst enemies, as Raji marries Rajashekar against his wishes and becomes pregnant for two months. Madhan's bike also gets stolen. The police arrest him and beat him up as the bike is used for chain snatching. Rajashekar comes to his rescue and agrees to keep him in his home, after which follows a melodrama between Madhan and Raji.

Madhu is a Chennai-based drug dealer. One of his drug-carrying trucks is nabbed by Rajashekar. Rajashekar seeks the help of the central vigilance team to seize Madhu's drugs and arrest him. Madhu orders his men to ram the van carrying him by a lorry and escapes from the hospital where he is admitted. Meanwhile, Madhan's aunt Dhanalakshmi passes away. At the same time, Madhan finds out about the thieves. The thief, also in Madhan's opposite gang, refuses to surrender due to his political influence and lack of enough evidence. The thief challenges Madhan to a bet race with him and tells him that he will surrender if Madhan wins, and his bike will be restored to him. However, in the race, the thief badly injures Madhan. Rajashekar helps Madhan win the race, and he gets back his bike. Later, Madhu's goons kidnap both Rajashekar and Madhan. In a fight that ensues, Rajashekar kills two of Madhu's goons and gets shot in a bid to save Madhan. Madhan realizes his mistake and, in retaliation, kills all the goons and leaves Madhu to get arrested.

The film ends happily with Madhan and Rajashekar getting united.
