Delhi Belly story begins with three friends Tashi (imran), Arun (vir das) and Nitin (kunal) who are also partners in crime. Arun has been deserted by his girlfriend and he is also having issues with his eccentric boss. On the other hand Tashi is all set to get married to the beautiful and hot Soniya (shehnaz). As for Nitin, he doesn’t realize that a hearty meal of Tandoor chicken at a roadside stall is going to change the life of his belly forever. While life goes normal for them, a crazy set of incidents take place and they come across a dangerous gangster (Vijay raaz). What happens after that forms the rest of the story.
