Walter Vanangamudi (Vishal (actor)) and Kumbudren Saamy (Arya (actor)) are half-brothers who constantly fight and try to outdo each other. Both brothers are petty thieves and get encouragement from their respective mothers. Walter's mother Maryamma (Ambika (actress)) encourages her son to steal and continue their "family tradition". However, Walter, an effeminate aspiring actor, is rather interested in arts than committing crimes. The Zamindar Thirthapathi (G. M. Kumar), referred to as 'Highness' by the community, takes an affinity towards Saamy and Walter and treats them as his own family. He constantly encourages Walter to take up acting seriously and to be friendly towards his brother. Walter is smitten by Police Constable Baby (Janani Iyer), from whom he attempts to steal after being dared by his brother to prove himself. She finds him completely amusing and eventually falls for him. He returns several stolen goods from his home and from Saamy to rescue her from being dismissed and goes to great lengths to impress her. Saamy falls for a college student named Thenmozhi (Madhu Shalini), who is initially intimidated by his rough ways but eventually reciprocates his love.
