Sunday, 9 November 1952. It should be remembered as a day of infamy but few know of a brutal massacre when police opened fire at an ANC Youth League event in Duncan Village in East London. In the cover-up that followed, the facts were almost lost to history. The focus was on the killing of Irish nun, Sister Aidan Quinlan, a doctor who ran a clinic in Duncan Village. Bloody Sunday follows the trail of the remarkable Sister Aidan to piece together one of the most tragic days of the apartheid era.
