Chinnakkannu (Murali) lives in a village with his maternal uncle Vellaiyan (Nassar). Vellaiyan asks Chinnakkanu to woo Poongodi (Prathyusha), the only daughter of Muthuraja (Napoleon), a rich Zamindar of a nearby village. Chinnakannu succeeds in his attempt to woo Poongodi, but on the day of wedding between Chinnakkannu and Poongodi, Vellaiyan interrupts and takes away Chinnakannu with him cancelling the wedding. A flashback is shown where Muthuraja is widely respected by everyone in his village. One day, he gets drunk and rapes a girl without consciousness. The victim is Vellaiyan's fiancé (Priyanka), who happens to be Chinnakannu's sister. Muthuraja realises his mistake and marries the victim. However, she dies during her delivery, and Poongodi is born to her. Vellaiyan plans to revenge Muthuraja by using Chinnakannu. Finally, after many events, Chinnakannu marries Poongodi.
