Muthaiya is the lead performer of a karakattam troupe based out of a village. Muthaiya's mother was his dance guru. Similarly Kamakshi is also a karakattam dancer in the nearby village and she performs regularly during temple festival of that village. Chinnarasu is the village panchayat board president and he sets an eye on Kamakshi. But Kamakshi hates Chinnarasu. To take revenge on her, Chinnarasu invites Muthaiya's dance troupe to perform during temple festival instead of Kamakshi's performance.

Muthaiya performs well and is widely appreciated by the villagers. Kamakshi also likes Muthaiya's performance. Kamakshi's father invites Muthaiya to his home. And to his shock, Kamakshi's father understands that Muthaiya is his nephew but does not reveal it to him. Muthaiya and Kamakshi fall in love with each other. Chinnarasu gets to know about Muthaiya and Kamakshi's love affair and plans to separate them.

Balaraman is Kamakshi's innocent brother-in-law who works for Chinnarasu. Chinnarasu persuades Balaraman to challenge a dance competition between Muthaiya and Kamakshi for which both accepts. In the meantime, Chinnarasu plans to kill Muthaiya during the dance program. His assassin, a butcher, throws a knife at Muthaiya, but Kamakshi saves him, thereby getting stabbed in her leg after the dance.

Muthaiya's mother gets furious upon realising that Kamakshi is her niece and takes Muthaiya along with her and also does not permit their wedding to happen. She reveals a flashback that Kamakshi's father is her own brother and he eloped with the jewels that were meant to be sold to meet the medical expenses of Muthaiya's father which led to his death. But Kamakshi's father arrives there and reveals the truth that while he went to sell the jewels, he was caught by the police suspecting him to be a smuggler following which he was jailed for a few years.

Now Muthaiya's mother realises her mistake and unites with her brother. Also she agrees for wedding between Muthaiya and Kamakshi. Chinnarasu accuses that Muthaiya and Kamakshi misbehaved in the temple and orders them to walk on fire in the temple to prove that they are pure. Muthaiya and Kamakshi successfully walk on fire while Balaraman exposes Chinnarasu's true identity before of the villagers. Balaraman pushes Chinnarasu on to the fire but Muthaiya saves him which makes Chinnarasu remorseful. Muthaiya and Kamakshi marry.
