It starts with Prakashan, narrating his story to Dr. Thomas. He talks about his father, Sreedhara Kurup, who runs a supermarket. Prakashan's father wants him to become an officer but Prakashan's interests lie elsewhere. After graduation, he is more interested in the activities of the village arts club than in looking for a job. He falls for a village girl, Uthara, who is his childhood friend. But her rich father, Mahadevan, arranges her marriage with another rich boy. The story builds up from here on. Prakashan, who works as a driver in Ponnu's house, accompanies her to her friend's house. The car breaks down. They stay at a lodge, waiting for a mechanic. During this, a drunk Shaji, upset about Ponnu not realising Prakashan's love, calls a policeman to raid the lodge and catch them, so that her marriage gets called off. This happens without Prakashan's knowing. On getting caught and later getting released, Ponnu faces backlash from her greedy relatives and Prakashan from his father. In anger, Ponnu decides that she will only marry Prakashan and not the ones her greedy relatives want her to. Her father and grandmother support this. Prakashan finally marries his dream-girl, but their marriage doesn't last even for a day, when drunk Shaji says that he was the reason for the raid. A misunderstanding in his statement leads everyone to believe that Prakashan also knew about this. Prakashan tries to prove his innocence but his efforts prove to be in vain. His father ousts him out of his house. After a year, Prakashan is finally found in a faraway place. His father requests him to come back as his mother waits for him everyday with a lot of hope and says that he can't break his promise to her. But when they come back, Prakashan's mother had already died of her illness. This leaves everyone devastated. Prakashan, after knowing that Ponnu is getting married, goes to her to bid a final farewell and gives her a bangle, bought with his hard-earned money as her wedding gift, and leaves. Fast forward to 5 years later, Dr. Thomas suggests that Prakashan should meet Ponnu for old times sake, considering that he had saved her from an accident earlier in the day. In the hospital, he finds out that she had been discharged. Finally he reaches, only to find that his father and his sister had been the ones taking care of a depressed Ponnu. His father explains that 5 years back, when he had left, Shaji, while explaining about Prakashan's innocence to Ponnu, got hit by a car and died instantly. After this traumatic experience, she stopped talking, moving and her wedding got called off. Her father died of a broken heart after seeing her condition. Her greedy relatives put her in a mental asylum, from where Prakashan's father found her and looked after her. Finally, all ends well, with Uthara getting cured and starting a new life with Prakashan.
