"Film City" is a light-hearted story of a chawl (slum) situated just next to (the actual) Film City, a studio complex at the centre of the Bollywood film industry. It follows the misadventures, antics and lives of its quirky residents as they try to piece together their own movie -- with the unwitting assistance of a Bollywood superstar, John Abraham. Raju, a spotboy (or gofer) is all set to make a movie on his mobile phone but it's main cast member hasn't the slightest clue he's in it.
