Krishna (Ajith) belongs to a middle-class family, where his father is a womaniser and brought up Krishna as a good for nothing fellow. Krishna is also an youngster who likes to waste time, by hanging out with his friends and roaming behind girls. Vaanmathi (Swathi) is the daughter of a rich business woman who is very arrogant and does anything for money. For example, she even abandoned her husband when Vaanmathi was a baby for money. Vaanmathi is a girl who grew up to be a bully, by bringing a bunch of friends in her vehicle and making fun of every guy they come across. Krishna and Vaanmathi play tricks on each other and fight after they met but eventually fall in love, but Vaanmathi's mother is not happy with that. She dislikes Krishna and considers him as her enemy #1.

She tries everything to break them. Finally she arranges a marriage between Vaanmathi and son of the Governor of Tamil Nadu. Whether Vanmathi and Krishna's love wins over the arrogant mother forms the story.
