Udta Punjab is a cracker of a title, and the way it opens tells us that it will go on the way it means to: with rolled-up sleeves ready for action, with characters who look as if they belong to Punjab, and speak the lingo right ( mostly) .
Most importantly, it reveals a willingness to go over to the dark side and show what drugs can do. They can ruin. They can kill. They can wish you were not alive.
