Seven years ago, Vivek "Vicky" Rai, the playboy son of the home minister of Uttar Pradesh, murdered bartender Ruby Gill at a trendy restaurant in New Delhi, simply because she refused to serve him a drink. Now Vicky Rai has been killed at the party he was throwing to celebrate his acquittal. The police arrest six guests with guns in their possession: a corrupt bureaucrat who claims to have become Mahatma Gandhi; an American tourist infatuated with an Indian actress; a Stone Age tribesman on a quest; a Bollywood sex symbol with a guilty secret; a mobile-phone thief who dreams big; and an ambitious politician prepared to stoop low.
