The main theme behind KK is the power of influence. Parents have total control over the child for some years. Once he grows up, his friends have considerable impact on his outlook and attitude. When he falls in love, he surrenders to his sweetheart. A problem child may grow into a responsible adult with the right peer pressure. An indifferent youngster may turn a new leaf on the advice of his beau. What does destiny have in store for a guy who does not heed to any of the three important groups of people in his life? Watch KK to find out. S.J. Surya is the Kalvan and Nayantara is his Kadhali.
