Tommy Singh(Shahid Kapoor) is an accidental rock star and a full-time user. making a song out of it, and the high-on-the-white-stuff youngsters at his raves love it. He loves it too, till the one day all the jollies-the money, the endless supply of the ‘chitta’ powder, the adulation- curdle. And his eyes light upon a battered-yet-not-beaten Bihari labourer(Alia Bhatt), who has become an unwitting victim in this vicious game, and he stutters, stops and starts to see.
Sartaj Singh(Diljit Dosanjh) is a corrupt cop, who is quite happy to turn a blind eye to the drug traffic, till one day it comes too close home. The feisty Dr Preet Sahni(Kareena Kapoor Khan), who runs a rehab clinic, becomes the other strong salutary influence on Sartaj, and the film takes an about-turn.
Anyone with half an eye open can see that this is not a film that glorifies drugs. The degradation of Alia’s character, both physical and mental, is horrifying. An addicted teenager’s spiralling down the primrose path is another of the plot’s see-see-this-is-what-drugs-can-do-to-you thread. It gets to the point where you want to say right, we get it, move on.
