Chandramathy, clad sloppily in a saree, wearing more jewellery than is becoming, and continually chewing paan, is the uneducated wife of Madhavan alias Madhu. They have four children - Kaadambari, twins Sivan & Parvathy and Kingini. Chandramathy has an old battle axe of a grandmother. She also has four stalwart brothers - Arumughan, Shanmughan, Gunashekharan and Digambaran.

Madhu and Chandra were married when the former was a nobody. Things are different now. He is a respected singer and composer, and has his share of fame and fortune. Uneducated though she is, Chandra is aware of their incompatibility in the changed scenario, and attempts to improve, even trying her hand at learning English. But she commits one faux pas after another and Madhu is ever at the receiving end of her follies. In comes Indulekha to complete the triumvirate of Madhu-Chandra-Lekha. Indulekha is a slim, svelte model and an ardent lover of Madhu's music. Complications begin.
