Raja (Prashanth), Sudhakar (Charle), Raghava (Chinni Jayanth), and Marudhu (Vadivelu) are good friends who stay together as tenants at Gandhimathi's house. After being thrown out of the house, they start searching for a new house on rent, but no one is willing to give their house for bachelors. Finally, they come to know a landlady (K. R. Vijaya) in search of a family as her tenants. A plot is hatched by, and all four bachelors dress up to be a family man (Sudhakar), his retarded brother (Raghava), his uncle (Marudhu), and his wife Lakshmi (Raja being the wife). Now, Raja's (who happens to be in a woman's attire) lady love (Suneha - debut) happens to be the landlady's daughter.
