Santhosh was the only son of a London-settled Tamil business tycoon named Krishnan and Janaki. He came to Chennai along with Janaki to attend the wedding of his cousin Lalitha alias Lalli's wedding. Lalli was Kavitha's best friend, and she too came to Chennai a few days before the wedding. Santhosh, a fun-loving person, developed an attraction immediately after seeing Kavitha, but Kavitha didn't reciprocate his feelings, and maintained a distance with Santhosh.

Slowly, Santhosh and Kavitha became good friends, and love later blossomed between them. Shalini alias Shalu was the daughter of Santhosh’s uncle Ravichandran's friend Jagadhalapradhaban alias JP, and she developed an infatuation towards Santhosh. Janaki got furious knowing about Santhosh and Kavitha’s love affair, as she thought that Kavitha was poor and from low societal status. On the day of Lalli’s wedding when they sent Santhosh away to buy some gifts for Lalli, Janaki and JP spoke ill of Kavitha and asked her to leave the place before Santhosh's return. When Kavitha was about to leave the place, Muthupandi suddenly arrived with his friend Karuppayya and was shocked to see her condition. He got angry, scolded everyone there for hurting his sister, and also took her back to Panpoli. Santhosh, who was still upset as Kavitha left him, learnt from Lalli what has happened the previous day. He went to the room where Kavitha stayed and found her horse clay doll, her favourite doll which Muthupandi made for her and modified by Santhosh after Shalu broke it out of anger and jealousy. While waiting for a connecting flight in Dubai, Santhosh escaped from Janaki and went back to Tenkasi instead, with the idea of heading to Kavitha's village. When he arrived in the village, everyone got shocked. Muthupandi didn't like Santhosh because of Janaki’s attitude and thought that he too would ill-treat Kavitha in the future.

Santhosh apologised to Muthupandi for the misunderstandings and requested him to get Kavitha married to him. Hence Muthupandi came with a challenge. He allotted an acre of agricultural land to Santhosh and asked him to do farming there. Santhosh, in order to prove his love for Kavitha, challenged him that he would cultivate one more bundle in the end. When Muthupandi agreed, Santhosh started work, although he didn't know farming. Santhosh tried hard to do farming, and somehow, he managed to learn cultivation. Krishnan came to Tenkasi to confront Kavitha and Muthpandi and bring back Santhosh. He saw Santhosh living a typical farmer's life, and eating plain rice with chilli powder and got triggered emotionally. He tried to convince Santhosh and asked him to come back to London. When Santhosh said that he believed in his love for Kavitha and didn't wish to return, Krishnan went to confront Kavitha, who was the cause for his son's condition.

Krishnan overheard Kavitha's conversation with her servant and realised that she too had been sleeping on the floor despite cold conditions and proper bed and was eating the same food as Santhosh. Krishnan felt overwhelmed thinking about the young lovers and blessed Kavitha. He also told her that their true love would win and asked her to stay strong.

Meanwhile, JP and Shalu wanted Santhosh to lose so that he would return. They sought help from a local goon named "Mark" Mayandi to distract Santhosh. Also, there was a factionist named Sivaji, a local rich man in the village. His son wanted to marry Kavitha at any cost. The cultivation was completed, and rice grains were bundled in both Santhosh and Muthupandi’s farms.

One night, when Sivaji's son tried to burn Santhosh's land, it backfired, and Mayandi intervened the chaos and got burned on his back. He also set the shed on fire where Santhosh was staying. Everyone tried to extinguish the fire and Santhosh rescued Muthupandi from a near accident due to the fire. Also, he saved Kavitha’s horse doll. On the day before the counting, Mayandi took a few bundles from Santhosh and placed it along with Muthupandi’s so that Santhosh would lose the challenge. The next day, Muthupandi revealed to his guardian, a railway manager that he added extra bundles in Santhosh's so that he could win. He also revealed that Santhosh was the right match for his sister. Santhosh won the challenge as he had cultivated more compared to Muthupandi, following which he agreed for their wedding.

Sivaji and his son got angry upon seeing this. His son planned to forcefully marry Kavitha. JP and Mayandi also got angry, and they plotted to murder Muthupandi. They kidnapped Kavitha but were beaten up by Santhosh and Muthupandi. A fight erupted in which Sivaji’s son was killed by Santhosh, who saved Kavitha, while JP and Sivaji were violently defeated by Muthupandi. When police arrived at the spot, Muthupandi took the blame for the murder and requested Santhosh to marry Kavitha and lead a happy life. He got jailed for seven years.
