Idhayakani (Vimal), who hails from the village Killiyoor, is a firm believer in nonviolence. The ongoing feud between his family and the family of Cheena Thaana (Gnanavel) from the neighboring village of Puliyoor is a source of constant worry for him. Though their rivalry began on a minor issue, many lives were sacrificed over the years. Idhayakani's father (Aadukalam Naren) is killed by Cheena Thaana. Angered by his son's death, Idhayakani's grandfather (Vinu Chakravarthy) retaliates by killing Cheena Thaana's son. Cheena Thaana vows to kill Idhayakani.

Meanwhile, Idhayakani meets Cheena Thaana's daughter Thamarai (Bindu Madhavi) at a temple festival and falls deeply in love with her. Chaos ensues when both realize who their families are, and the respective sets of parents and villagers object to their romance. Idhayakani marries Thamarai at a temple, and Cheena Thaana gets killed by Idhayakani's grandfather's henchmen. Thus, Thamarai develops hatred towards Idhayakani for her father's death. According to Panchayat, Thamarai goes to Idhayakani's home with her family in order to kill Idhayakani, but they fail in their attempts. When Chitappa (Ravi Mariya) hears that Thamarai is pregnant, he is determine to kill her child, but Thamarai's uncle Surya (Soori) tries to give strength tonic instead of poison to Thamarai, which makes her safe. In the climax, Killiooru organizes a Kabaddi match in Puliooru. Chitappa arrives at the place by kidnapping Thamarai and her mother (Vanitha Krishnachandran), but Idhayakani's uncle Koushik (Singampuli) was kidnapped instead of Thamarai. It turns out that Surya had saved her. Chitappa arrives to kill Idhayakani, but the presence of cheerleaders makes him undergo a change of heart. He then dances to the tune of Gangnam Style and accepts Idhayakani wholeheartedly.
