Tamil (Vimal) was raised by his grandfather (Raj Kiran) singlehandedly in a village; 25 years later he's working at a Chennai IT company, living in a posh apartment. Tamil meets Karthika (Lakshmi Menon), a medical student at a traffic signal and it is love-at-first-sight for him. He follows her, and in no time she reciprocates his feelings. Tamil is now selected to go to US in three months and he brings his grandfather to the city to spend quality time before he leaves. The rest of the film is how the old man with a heart of gold creates havoc and nuisance in the life of Tamil, residents of the residential apartment, and even in the American consulate.
