When he falls in love with a wealthy co-ed (Asin) who demands emotional honesty, a working-class welder (Vijay) who thought his past was safely behind him is forced to revisit unpleasant memories. As it turns out, he left home more than a decade ago and has never returned out of spite for his older brother (Prakash Raj), who tricked him into taking the rap for something he didn't do. Will going home again change everything -- or make it worse?
