Bharath, Arun, Arjun and Padmakumar are four college students who, disillusioned with the widespread corruption, decide to deliver their own brand of justice. Donning black dresses and helmets and arriving on motorbikes, they chop off the hands of the guilty. Soon, they have their own website with people sending them emails with their grievances. The official against whom most complaints are registered becomes their next target. This makes them popular with the common man but the police is under pressure to capture them.

The aforementioned movies with this theme have all had big name heroes like Kamalhassan, Vikram and Vijayakanth leading the fight against corruption. This resulted in similar story arcs with familiar components like the hero not getting caught by the police until the climax, a tragic flashback explaining the reason for his acts and a longwinded speech at the end. Having four unfamiliar faces eliminates most of these and lends a certain unpredictability to the proceedings. The policeman on the students' track is not always a step behind them and the movie surprises us with the path it takes (like the politician's way of countering their popularity).

The movie has a fast pace with only one of the two romantic tracks, the one between Bharath and Gopika, having no impact on the main story and so dragging the pace down a little. There are many little twists and turns(like the students' way of checking their email after knowing that their usual internet cafes are under police surveillance) that keep the story moving. Things like the policeman uncovering their identity happening earlier than expected, is another reason for the fast pace. The movie closes things off with a wonderful climax. After successfully raising the tension with their plan to kill the politician, the movie ends in a way that is unpredictable, completely new and almost exhilarating.

The entire cast does their job well though there are no standouts. Bharath(from Boys , Gopika(Cheran's Malayali lover in Autograph and Pranathi(Sarathkumar's wife in Gambeeram ) are the only familiar faces to us. The soundtrack, which was a huge hit and a primary reason for the movie's success in Malayalam, translates well to Tamil. The songs all have fast beats and contain a lot of variety. Lajjavathiye... is very catchy and music director Jessie Gift's unique voice and accent add to the song's appeal. Annakili... and Unthan Vizhimunai... are the other catchy numbers that have us humming real soon. Unfortunately the picturization does not do justice to the songs. They lack not just imagination but even basic choregraphy and the song sequences simply have some regular scenes put together randomly.
