Shiva (2006)

Shiva (Mohit Ahlawat) is the good police officer, bent on doing his duty, while the rest of the police force, excluding his friends, are all the villainous cops. This extends to the home minister who threatens Shiva after he punishes wrong-doers, some of whom work for all these high-profile officers. Shiva ends up arresting Bappu, a criminal-turned-politician and finishes his whole gang in a bid to un-corrupt the 'system', about which the home minister warns Shiva.
