Vibrant and evocative, this socially relevant family drama revolves around two good friends, Anirudhan and Sukumaran. Anirudhan is from a village, but due to his job as a salesman for a pharmaceutical company, he travels to many towns. However, Anirudhan remains true to his conservative traditional upbringing. On one occasion, he happens to meet and befriend Sukumaran, who is also a travelling executive, but from a sophisticated, urban background.
When Anirudhan's grandmother gets injured, Sukumaran travels back home with him and during the trip, falls in love with Anirudhan's sister, Sujatha. Soon, Anirudhan and Sukumaran turn their friendship into a relationship by marrying each other's sisters. Anirudhan marries Sukumaran's sister Neelima, while Sukumaran marries Anirudhan's sister Sujatha.
This seemingly ideal situation turns into a nightmare when conflicts develop between husband and wife due to marked differences in culture, tradition, belief system and lifestyle. Will the strong friendship between Anirudhan and Sukumaran survive through all the troubles? Can the couples find a way to get over their differences and create a happy and harmonious life?
