Kamarasu(Murali) is an epitome of sacrifice and loyalty. He is not just the apple of his mother's eye but also the most wanted guy of the village, in terms of appreciation. Basically he plays the character of a guy too good to be true and too hard to believe too. Apart from looking after his mother he is brought up in the house of Srividya who has three daughters. Srividya treats him as one among their family. Murali is so indebted to the family beyond all human reason that he actually takes the blame of his father's accidental death by Srividya's daughter. Laila plays the role of the flower vendor in the film who is in love with Murali, the only solace in his troubled life. He continues his selfless service at Srividya's place when one day he overhears that Srividya is about to rewrite a part of her will also including Murali in the inheritance. Not wishing to inherit any property he leaves town without informing anybody. While the whole family of Srividya is set out find Murali, they meet with an accident and all gets critically injured, all of them in desperate need of a vital organ transplant. Murali on hearing this comes to the hospital and asks the doctor to use his organs and save others. When the doctor refuses Murali jumps from the hospital top floor and commits suicide. Finally his organs are used to save the whole family.
