In 1987, Sakthi joins a college in Sivagangai, where he meets his classmates Joseph and Meenakshi. Sakthi and Joseph are hostel roommates and are very close. Meanwhile, Sakthi falls in love with Meenakshi, after a mix up of photographs. She happens to be the daughter of Periyavar, the headman of a nearby village. Periyavar and his family show at most casteism and go to the extent of killing anyone involved in an inter-caste marriage. Meenakshi fears for her father as he might kill Sakthi if he gets to know about her love. Sakthi and Joseph get expelled from the college hostel following a fight with another classmate Syed, and come to Meenakshi's village to stay. Joseph meets Swarna in the village and develops a liking towards her, for which Swarna too reciprocates. It is revealed that Swarna is actually Meenakshi's elder sister. Periyavar finds about Swarna's love affair and sets the stage to kill Joseph.
However, Joseph and Swarna elope from the village and get married with the help of Sakthi and Meenakshi. Periyavar's henchmen trace their location to a hut and beat up Joseph. In the process, Joseph is killed, then they pour petrol over his body and set fire to the hut. Swarna is taken back to her village and locked up in a room. In the meantime, Periyavar finds about Meenakshi's love affair and sets a plan to kill Sakthi. An angered Swarna kills Periyavar with a sickle before he could kill Sakthi. Thus, Swarna sets a full stop to Periyavar's honor killing practice. Sakthi and Meenakshi get united at the end.
