The story of 'Thoranai' reminds one of the story of the crow filching the vadai from the old lady and one can see the change in the 'thoranai' of the audience as they come out of the theatre after watching the film.

Vishal generally gallivants around town with nothing special to do. One day on returning home, he sees his mother crying. He caringly asks his mother the reason for her tears. "I am reminded of your elder brother who went missing 20 years back," she says. Vishal promptly promises to trace his brother and leaves for Chennai right away!

He arrives in the big city and ends up making foes of the 2 dons Prakashraj and Kishore. There ensue the usual fights and songs and halfway we realize that Kishore is the lost brother of Vishal. Of course, the film goes on to see Vishal fulfill his promise to his mom.

The film is quite racy for the first 20 minutes or so and slowly degenerates into a sluggish drag, testing our patience. 'Thoranai' becomes a real 'sodhanai.' Vishal is free with his punch dialogue "Nee adicha pannam, naan adicha ponnam" to such an extent that even in the darkness of the theatre one can see the rasikas begging him to stop!

Vishal gets bashed up silly by Kishore's henchmen so when he appears like a prize apple in the next scene, it is more hilarious than a Vadivelu comedy scene and one collapses into guffaws!

Talking of comedy, we have Vishal fighting with the goons alternating with singing duets with heroine Shriya and amidst this, we have the comedy duo Santhanam and Paravai Muniyamma keeping us in splits. The ever intoxicated Mayilsamy also gives some relaxing moments.

The Prakashraj-Kishore episodes remind us of the old film 'Agninakshatram.' Without knowing who Vishal is, Shriya falls for him. Her character is as skinny as her appearance. The cinematography and music are enjoyable. Vishal's never changing 'thoranai' makes for boredom.
