Kaushik is a happy-go-lucky guy with no sense of responsibility. He is young, carefree and spends his time roaming around his village along with his uncle Veeran Selvarasu. Meenalotchani, is the girl he is love with for the past three years. Eventually after many attempts at trying to woo her, with the help of his uncle, Kaushik successfully captures her interest and love. 

Meenalotchani has four brothers, all of them really kind and protective of her, especially her elder brother. Meanwhile, Kaushik approaches her family to formally ask her hand for marriage, only to get disappointed as they refuse him. The couple try their best to convince both their respective family to no vain, so they decide to elope and get married under Veeran's blessings and support.

Though the familes are furious with their decision, Meenalotchani's brothers finally understand that Kaushik is a good natured guy, and hence excuse the newly wedded couple. A few days later, in a shocking turn of events Veeran Selvarasu kills his own nephew Kaushik. Finding out why he does that forms the crux of the story. 

Both the film's leads; Kaushik and Meenalotchani has delivered a decent performance, especially the latter has done a good job. Veeran Selvarasu has directed the film and has also played a pivotal role. Though, he has done a decent job at the directorial department the movie lacks an enthusiasm which keeps the audience hooked to the film. 

In the other hand, Veeran has done a good job as a supporting actor. Dharma Prakash has provided the tunes for the film, and his background scores are much better than the songs. Mahesh's cinematography skills come to the fore and he has shot well.

In short, Veerathevan, could have been much better.
