This evocative drama opens with Venu (Mohanlal), mournfully bringing flowers to his beloved wife's grave. Through his reminiscence, his story is narrated in flashback. Venu was an educated young man who worked for a wealthy businessman Menon (Thilakan) at his tea plantation. After being fired, he tried to get his job back by playing music for Menon's only daughter, Sarojam (Urvashi)
Sarojam eventually fell in love with Venu and expresses her wish to marry him. Wanting to keep her unawares about her fatal condition, aplastic anaemia, Menon was ready to do anything for her. Menon tells Venu about the illness and asks him whether he was ready for the marriage. Menon offers him all the wealth and the complete authority of his family business. Venu, whose family is in a dire state, accepts the offer and gets married to Sarojam.
Initially, he pretended to love her as he felt sympathetic for her and wanted to make her happy always. However, gradually he falls in true love with her and an inseparable relation blossoms between them. Sarojam gives birth to a daughter, Ammu.
When Ammu is a few years old, Sarojam develops severe symptoms of the disease. Dr. Menon (Soman) suggests that bone marrow transplantation has a chance of recovery in her. After the procedure, Sarojam seems to recover but soon her condition worsens and she dies in the hands of Venu.
Then we are shown the first scene, which was Venu standing aside Sarojam's grave. After a while, Unni, a close friend of Venu comes there to inform him that his daughter Ammu is also affected with the same disease. Venu is shocked but he was not allowed to cry even as Ammu should never know about this.
The heartbroken Venu returns to his bungalow with Ammu. There he had a strange visitor named Hari (Vineeth), an unemployed young man, who came there with a recommendation letter for a job. Soon, Venu realises that, what has happened in his and Sarojam's life is getting repeated in his daughter's life too, through Hari. He allows Hari to stay there and in the last scene, it is shown Venu calling Hari to his room, in a similar way he was called by Menon for Sarojam's proposal.
