Karthik Swaminathan (Dhanush), referred to as 'Genius' by his friends, is a Freelancer photography who aspires to become a wildlife photography like Madhesh Krishnasamy (Raviprakash). His friends Sundar (Sunder Ramu), Shankar (Mathivanan Rajendran), Padmini (Pooja Devariya), and Vindhya (Shilpi Kiran) support him and his sister after the death of their parents. One day, Sundar introduces Yamini (Richa Gangopadhyay) as his girlfriend to Karthik and his friends. On their first meeting, Karthik and Yamini have a bitter experience but slowly develop a special bond. Karthik tries to stay away from Yamini, but a sequence of events brings them closer. Eventually, Sundar's father arranges for Karthik and Yamini to be married. After their wedding, Karthik learns that Madhesh had used a photograph that he had taken to win a national award. After this incident, he turns into an alcoholism. Yamini supports him, hoping that he will succeed one day. Days later, Karthik's drunken fit leads to Yamini's miscarriage, after which she stops talking to him. This makes him come to terms with reality, and he mends his ways. He finally gets a break and becomes a professional wildlife photographer, and one of his photographs gets nominated for an International Photography Awards, which he wins. On this occasion, Karthik thanks everyone for their support and Yamini for her faith in him and declares his love for her. Yamini finally relents and talks to Karthik as the film ends.
