The film begins with Kutty (Vijay (actor)) waiting at the Pune rail station for the train back to Chennai. As he continues to wait, he tears off a paper scrap from a pillar that reveals a carving of the name "Rukmani". The train arrives and Kutty boards a cabin that is boarded by college students from Chennai who are musicians. During the train journey, Kutty starts singing "Innisai Paadivarum", which catches the attention of everyone and they all begin to sing along with him. After finishing the song, the students applaud Kutty for his singing and ask him whether he's a professional musician and his reason for coming to Pune. Kutty denies this and reveals that he's an ex-convict, having been released from jail after 8 years. When asked why he was imprisoned for so long, Kutty explains the reason for his conviction as the film goes for a flashback.
