The film features the story of three bank employees and their wives. Bank manager Prakash (Suresh Gopi) is an ideal husband, while his wife Sumati (Urvasi) is emotional and complaining. They have a perfect family with a smart boy, a terraced house and a maruti car. Accountant James (Mukesh) is a womanizer and his wife Elsi (Lizy) is fed up with his activities. Cashier Gowthaman (Jagathy Sreekumar) is struggling to adjust with his North Indian, Hindi-speaking wife Ambika as he has to take care of all the household chores and look after their baby. There is a tangential storyline involving a suspicious husband named Thankappan (Kuthiravattam Pappu) and Radha, a servant in Prakash's home. Then enters Renuka Menon (Sudha), a beautiful widow who arrives at the bank to open an account and gets charmed by the handsome Prakash. Sumati leaves for her parents' (Jagannatha Varma and Kaviyoor Ponnamma) house to celebrate her father's birthday while Prakash is busy with a visit by the regional manager (Janardhanan) at the bank. Will Prakash remain faithful to his wife??
