Documentary examining why followers of the Sikh religion were marked out as a 'martial race' under the British Empire, and how thousands of Sikh soldiers valiantly laid down their lives for Britain's freedom across two world wars. With contributions from eminent historians, military experts and war veterans, the film features the last-ever interview with legendary WW2 Squadron Leader Mahinder Singh Pujji, and the first television broadcast of a rare audio recording of a WW1 Sikh prisoner of war, handed to Britain in 2010 after 94 years in German hands.
