I watched the movie, and its awesome.and the story of Four parallel tracks, that of a Punjabi rockstar.
Tommy Singh ( Shahid) a Bihari migrant, Kumari Pinky ( Alia) ; a Sikh cop, Sartaj ( Diljit) and a doctor, Preet ( Kareena) address the insurgence of the drug menace in Punjab. Their lives are sometimes linked to one another but usually not.
