Vedalam

Ajith and his sister, played by Lakshmi Menon, make their way into Kolkata in order to pursue Lakshmi Menon's education at a fine arts college. Ajith starts working as a taxi driver to make ends meet. 

While going about his business, Ajith informs a cop about a criminal's whereabouts, as requested by the Kolkata police who seek the help of all taxi drivers and ask them (drivers) to tip them off about all the wrongdoers, spotted anywhere in the city. 

Thanks to Ajith's rectitudinous, he lands himself in the soup when the affected ruffians decide to murder him for his law-abiding act. To their surprise, Ajith fights back and how? He simply transforms into a cold-blooded murderer and goes on a rampage. Who is Ajith? What is his past? Why is a killer wearing the mask of an innocent taxi driver? Answers to these questions forms the crux of Vedalam.
