Sidharth (Aamir), is a Mumbai 'Tapori' and a boxing champion. His older brother, Jai, works for Raunak Singh, who now rules their 'Basti' through terrorizing its people and collecting 'Hafta' from merchants. Sidharth idolizes his father, a freedom fighter, whom he saw falling to his death as a child. This effects Sidharth trough his adult life.
Sidharth meets a young woman, Alisha (Rani), who rides with a motorcycle gang and Charlie (Deepak), the gang?s leader. Sidharth also meets Hari, whose idealism reminds him of his father. Hari?s social work in the community poses a thread to Raunak Singh?s evil empire. What happens to Hari changes Sidharth?s life forever. How Sidharth breaks Raunak Singh?s chains of 'Ghulami' around the community forms the crux of the story.
