Singham is one of those typical 'hero-style' Indian movies.
If you want to have a taste of it without paying, it is legally available on Youtube.
The plot is simple: an incorruptible village police inspector is transfered to Margao, Goa, after crossing a well-connected criminal.
Said criminal is trying to make him breakdown, and his police work is interfered by his superiors, who are in the criminal's pocket.
In short, it shows the kind of immunity that people can get through corruption.
Oh, and it struck me as 'Telugu people won't leave me alone', since two major actors are Telugu movie actors ;)
