K [John Abraham] is a stubborn and obnoxious guy, who does exactly what he wants. A chain smoker, he feels nothing can come between him and his cigarette -- not his wife [Ayesha Takia], his friend [Ranvir Shorey] or his life. Till he encounters Baba Bengali [Paresh Rawal].
Baba Bengali has his own set of draconian laws to stop people from smoking. He guarantees results, provided his clients obey his orders to the T. But K revolts and pays a heavy price for it.
