Billu (Jayam Ravi) is the son of Mudaliar (Vijayakumar). Mudaliar is much loved and respected by people of his locality and Billu is almost like a foster son to every person in the locality. Billu takes an instant liking for Susi (Bhavana) the moment he sets his eyes on her at the railway station. Susi, who has arrived from Bangalore to Chennai, is all set to stay at Sait's (Cochin Haneefa) place and Sait, who has worked for Susi's father Chidambaram (Lal), a dreaded thug, earlier, has changed ways but retains his respect towards him nevertheless. Susi, who has been craving for love and concern since young, gets impressed with the bonding that the Royapuram residents share. When a Godman predicts that Susi is the one for Billu, she is taken aback. She dreads her father to a great extent and fears that things will go topsy-turvy if their relationship blossoms into love. But soon, she realizes that she cannot camouflage her feelings towards Billu and enjoys being in the company of Billu and his friend, when the unexpected occurs. Susi acts peculiar when a long lost friend meets her at a restaurant. She denies knowing her despite her friend Revathi's attempts to talk to her. Feeling insulted, Revathi walks away, much to the dismay and confusion of Billu and his friends. Susi, who gets emotionally high-strung, leaves the restaurant in a jiffy too. Susi, at this juncture, comes out with the truth to Billu. Affected with a condition called 'post traumatic event disorder' after an accident, Susi has forgotten events that happened in a span of three years. Billu, who takes her to the doctor (Raghuvaran), learns that this condition can be cured, but when she does get cured, Susi will not be in a position to remember whatever happened and whoever she met at Chennai-Billu included. This disheartens Susi to a major extent and she persuades Billu to promise her that he would never leave her, even if she were to forget him due to her condition. Billu promises her that he would never leave her, come whatever may. Billu's conversation with Chidambaram infuriates the latter and he immediately arrives to Chennai with his goon men. When he is all set to leave to Bangalore with his daughter, the residents rise to the occasion and flock against Chidambaram. Deciding to play it safe, Chidambaram agrees to the engagement between Billu and Susi and cunningly, thrashes Billu after making him arrive at a place far from his locality, at the outskirts. The helpless Susi travels along with her father, escorted by his men, to Bangalore. When Billu meets Susi at her residence, he gets nothing less than shocked as she has been cured and she fails to recognize him. But Billu, who had given a word to his beloved that he would never leave her, is not the one to relent. How he tries relentlessly to convince her and what happens with Susi forms the rest of the story. more»
