Story: Before I start off the review for this movie, let me go over the career of Vijay before and after this mega-hit. Naalaya Theerpu did fairly well in the box office but was not a great start; later his Sendoorpandi, Rasigan, Deva, Manbumigu Manavan etc were hits where as Chandralekha was his only flop. After this film Poove Unnakaga, Vijay's films like Vasantha Vasal and Kaalam Ellam Kathiruppen were flops.
However, this film was his first mega-hit which gave way to other mega-hit films like Once More, Kadhalukku Mariadhai, Love Today, Naerukku Naer, Ninaithen Vandhai, Nilaave Vaa etc which were all mega-hits in their own right. Now with the review. Stephen (Nagesh) and Nambiar have been college day best friends and so are their children Jaiganesh and Vasudevan. Jaiganesh's family members are Christians whereas Vasudevan's are Hindu. Jaiganesh's son is Lawrence and Vasudevan's daughter is Anju Aravind. Robert is the brother of Jaiganesh and Janaki is the sister of Vasudevan. Both of them as described very well by a lad; fell in love with each other. Against their families will, they marry each other and run away from their homes.
Ever since then, both families hate each other and to solve this Raja (Vijay); the son of Robert and Janaki; and his friend Charlie come to the village. Though his uncles hate him, his grandparents, aunties and uncles love Vijay but none go against the word of Jaiganesh and Vasudevan; hence Vijay and Charlie find accommodation in the house of a loud, frightful Velingiri.
Later, both of his aunts appear before him with marriage proposals and to avoid any more, he says he is married to a Hindu-Christian like himself. Here comes Sangeetha, posing as Vijay's wife and convinces the rest; causing Vijay to suffer a bit. However, when Vijay gives her the duty of a wife, she reveals that she is the real child and only daughter of Robert & Janaki and asks Vijay why he is acting as the grandson of Nagesh & Nambiar.
Now it is his turn to reveal his truth and the director plots this very carefully. Vijay struggled on his way to get a job after getting First Class in B-Com studies. Next to his rented out house; which he shared with Charlie, was a ladies hostel which featured Anju Aravind. As she and her group were trying to find a good tune to a song for a contest, Vijay indirectly helps her and Vijay falls in love while she treats him as a good friend. As he was about to notify Anju Aravind, of his love for her, she notifies Vijay of her love for Lawrence.
Hearing their plan to marry without their parents consent because of the Robert-Janaki problem, Vijay decides to pose as the son of who ran away couple. Now, both Vijay and Sangeetha carry out this mission and when Vijay is seen helping out the lovers in their ways of marrying, Anju Aravind's father gets notified of this and so the news as fire, gets spread quickly and both families now think they have run away and want to kill the members of the other.
Meanwhile, Vijay has rejoined the friendship of the aunts and the grandparents so the uncles and the lovers is his main concern. He does this at once in style. After the marriage, the truth of Vijay's appearance is revealed, and when Vijay is asked to marry Sangeetha, he replies a "no" for a good reason.
