Director Rajasenan, brings together Jayaram and Urvashi, for his new family entertainer Madhuchandralekha.  

The story revolves around Chandramathi (Urvashi), a coarse, disheveled character. Chandramathi has a clutch of equally coarse brothers (Bheeman Raghu, Harisri Asokan, Johnny) and grandma (Sukumari). She is uneducated, dresses crudely and always chews betel leaves. She had in fact fallen in love with her music teacher Madhavan alias Madhu (Jayaram). One day Chandramathi kissed him in public and that incident forced him to marry her. Madhu ends up as a playback singer after his marriage. They have four children - Kaadambari, twins Sivan & Parvathy and Kingini.

It can be described as an incompatible but happy marriage. Madhu loves his wife, even though they are out-of-synch, because he believes that it is she who brings him luck. Madhavan and the kids tolerate her, as she even spits betel juice accidentally on others and is known in party circles as “kolambi”.

But things seem to go out of hand when Indulekha (Mamta), a sophisticated girl urban model-cum-singer and an ardent lover of Madhu's music, enters the scene. Lekha soon finds a place in the hearts of the family members. Kids started to avoid Chandramathi because they want a stylish mammy like Lekha. Chandra is aware of their incompatibility in the changed scenario, and attempts to improve, even trying her hand at learning English. At last Chandramathi thinks Lekha will be the perfect wife for her husband and a good mother for her children. For uniting Madhu and Lekha she leaves home with her younger child Kingini. This incident totally changes Madhu's life. How Madhu's friends go about uniting Madhu and Chandramathi forms the rest of the story.

Jayaram, as the understanding husband who tolerates the strange ways of his wife, has enacted his role well. His underplayed emotions give the film a veneer of acceptability. He looks good in costumes designed by his wife Aswathy Jayaram. But the film solely belongs to Urvashi. If Madhuchandralekha manages to create ripples at the box-office, it will be only because of her. Considering this is the story of a playback singer, one would expect the songs to be of some importance. But the songs, composed by M Jayachandran, are just used as fillers to fill in narrative gaps. The others in the cast have just walk-in parts. Mamta seems very modern in her costumes. Overall the movie is hilarious.
