Today is the biggest day in Jamal Malik’s life. A penniless, eighteen year-old orphan from the slums of Mumbai, he’s one question away from winning a staggering 20 million rupees on India’s "Who Wants To Be A Millionaire?" But when the show breaks for the night, suddenly, he is arrested on suspicion of cheating. After all, how could an uneducated street kid possibly know so much?

Determined to get to the bottom of Jamal’s story, the jaded Police Inspector spends the night probing Jamal’s incredible past, from his riveting tales of the slums where he and his brother Salim survived by their wits to his hair-raising encounters with local gangs to his heartbreak over Latika, the unforgettable girl he loved and lost.
