Zakhariah (Jagathy Sreekumar) is a private banker who has returned from the gulf. He has a very straight forward life with his wife Molly (Uravashi) and their daughter Teena. His life takes a turn when one of his clients Girija Menon (Mukesh) gets close to him. Menon is a textile businessman and a womanizer who is married to an orphan Sreelakshmi who cannot conceive a child. Soon, Zakhariah begins to transform himself in his style and appearance. He gets an open offer from Urmila (Jyothirmayi), wife of an architect that she is willing to continue a relationship with no strings attached. From then on, Zakhariah begins to ignore business, family and gets into an illicit affair.
