Tamil cinema and realism do not traditionally go hand in hand. But even by those usual standards, first-time director Madhuravan's outing stands out as one of the most contrived to hit the screen in recent times. But he does show a flair for comedy and that makes the movie watchable.

Saravanan(Prashanth), orphaned by his dead mother - a mental patient - is adopted by a childless couple (Manivannan and Radhika). Theirs is an inter-caste marriage. At college, he runs into Kavitha (Rambha), the granddaughter of caste-obsessed Sengodan(Rajan.P.Dev). The triangle is completed by Aavudayappan alias Armstrong(Livingston), a US-return who is smitten by Kavitha.

With a little unintentional photo-swapping by the marriage broker, the parents of Saravanan and Aavudayappan (the fathers have the same name) both think they have an alliance for their son with Sengodan's family and show up at Kavitha's house at the same time. Romance flowers between Saravanan and Kavitha, who assume they are going to wed, while Aavudayappan continues to dream of Kavitha.

A series of contrivances allows this comedy of errors to carry on till the engagement where announcement of the groom's name causes all sorts of confusions. Sengodan is now against the Saravanan-Kavitha union since Saravanan's parents are of different castes. This sets the stage for the climax where past secrets are revealed and matters cleared.

One needs a really long stretch of imagination and total suspension of disbelief to accept the goings-on in this case of mistaken identities. But once you do that, the movie manages to provide some fun. While few scenes are laugh-out-loud funny, many bring a smile to our lips. Vivek plays a large part in this with several funny one-liners. Chalk up one more for Vivek after Vaali

Prashanth is competent but the movie is certainly a blip in his recent resume of hits like Jeans, Kannedhire Thondrinaal and Kaadhal Kavidhai. Rambha and Livngston don't have a lot to do. Among the older cast, Rajan.P.Dev and Radharavi stand out. Manivannan and Radhika are rather subdued with nothing much to do. There are three songs in the first half hour and considering their quality, that is three songs too many. None of the other songs is impressive either.
