Plot

Kutty is a good-hearted soul, but unfortunate incidents tend to portray his ruffian side whenever he encounters the girl he loves. A bizarre incident brings them closer and yet keeps them apart.

Kutty wants to become a singer while working in an audio shop run by Mani. His songs are appreciated by a college student Rukmani and each time when she wishes to meet him, circumstances project him as a transitive element. He also becomes the cause for Rukmani losing her eyesight and repents for it. He starts to love her and he regularly writes to his mother about the development of love he has for Rukmani. When his mother dies, she offers her eyes to Rukmani. To meet the cost of the eye transplant, kutty offers his kidney to a Pune-based richman. While returning home he inadvertently becomes an accomplice in creating explosives and he's arrested. Having regained her vision, Rukmani, who had studied for IAS, becomes a Collector and when Kutty tries to contact her, he is still the rowdy element in her mind.—Anonymous

Kutty is an aspiring but struggling singer who works for a local cable provider Mani. He is unable to get recognition and a stage to exhibit his musical talent. Rukmini "Rukku", a college student, is new to the locality where Kutty stays, and on hearing Kutty's voice, she becomes his fan and decides to seek him and encourage his talent as his voice resembles that of her late father. However, Rukku always catches Kutty in negative situations and, not knowing that he is Kutty, develops a hatred for him as she feels that he is a rowdy. Once, when Kutty is pickpocketed, he pursues the pickpocket to Rukku's college. In the process, he accidentally drops a bottle of acid to the ground, which causes Rukku, who is present at the spot where the acid bottle fell, to become blind.

Kutty is horrified when he finds out that he is the reason Rukku had become blind. To make amends, he decides to become her close companion and help her in every way possible. Soon, love blossoms between the two. When Kutty's mother dies, Kutty finds out that her eyes had been donated. He decides to arrange the operation to restore Rukku's eyesight with his mother's eyes, but as the price of the operation turns out to be very high, he accepts an offer from a Sikh man to donate a kidney for his Pune-based father for Rs. 40,000. Having paid for Rukku's surgery, Kutty leaves for Pune to donate his kidney. While waiting at the railway station to return to Chennai, he is framed as a terrorist and arrested.

Seven years later, Kutty is released from prison and returns to Chennai, only to find out that Rukku has moved out of their locality and is now a collector, her eyesight having been restored as well. But Rukku, on seeing Kutty and not knowing that he is Kutty, orders him to be arrested, in revenge for his "rowdy activities" in the past and for making her blind. But when Kutty begins to sing, Rukku realises that the "rowdy" she had arrested is none other than Kutty. She apologises for misunderstanding him, and they happily embrace, rekindling their relationship.
