As a little boy, Karthik (Vijay Antony) is a brilliant student but already shows signs of criminal behavior, forging his friend's parent's signature on a mark sheet. Sent home from school early for this misdeed, Karthik is shocked to discover his mom in bed with his uncle. His mother begs him not to tell his father, but he does so, and his father commits suicide. Karthik's mother and uncle continue their relationship; Karthik then kills his mother and uncle by setting the house on fire. He is sent to a juvenile home where he grows up. On his release, the warden gives him the address of another of his uncles and asks him to concentrate on his studies.
