Vinduja Menon, Thilakan, Srividya, K. P. A. C. Lalitha, Sreenivasan, Nedumudi Venu and Innocent played prominent supporting roles.

[1] The film deals with the relationship between siblings Unnikrishnan (Mohanlal) and Meenakshi (Vinduja Menon) who have an almost 30 year age difference between them.

The movie begins with an older man's dream; Unnikrishnan is roused from his house and told to come in haste to see his father (someone Unni has long believed to be dead).

An astrologer interprets the dream as a harbinger of Easwara Pillai's death and advises Unni to do the last rites for his "dead" father.

The story flashes back to Unni's youth when he was living in his ancestral home with his parents, Easwara Pillai and Devakiyamma.

But in a twist of fate, an amorous relationship takes a second bud between Devakiyamma and her husband Easwara Pillai and she becomes pregnant.

Soon after in a heated moment, Unni scolds his father and Easwara Pillai leaves town as he is devastated by the recent happenings.

Ramakrishnan's wife is also involved in changing Meenakshi into a complete modern girl by sending her to competitions and beauty pageants.

Meenakshi repents and goes back to the village to meet with Unni where she realizes that he has become mentally unbalanced after the trauma of seeing her in the accident and she decides to spend the rest of her life taking care of him.
