Karthi- a Tamil Hindu Brahmin boy (Dulquer Salmaan) and Riya- a Christian girl (Malavika Mohanan) elope one early morning to Ooty, fearing that the elders in the family will not accept their inter-religious relationship. They return to their respective homes after a couple of days after having a fight. They convince their family members that they hate each other and vow never to see each other again. But their fathers plan to reunite them thinking that they have broken due to immaturedness and ego problems. Riya's father is a friend of Karthi's father. Riya's family [without Riya] visit Karthi's home and invite them to Riya's marriage.
