A 5 year old girl from Pakistan gets separated from her mother at an indian railway station. Lost and hungry she finds shelter at the home of Pavan, an ardent devotee of Hanuman, hailing from a robust wrestling family. Bajrangi Bhaijaan is the moving story of Pavan's quest to unite the child with her parents against all odds. Set against the backdrop of colourful Chandni Chowk, the film travels from the heartland of Punjab, through the deserts of Rajasthan, over the snow-capped mountains of Kashmir. Bajrangi Bhaijaan tells the story of how Pavan moves heaven and earth to fulfill the promise he made to the girl from across the border.
