Tainted Heroes tells the story of how the African National Congress (ANC) – once a marginalised organisation within the South African political landscape – rose to power in the aftermath of the Soweto Uprisings in 1976. The documentary deals with the organisation’s military training received in various African countries as well as the lesser known story of how the ANC underwent strategic training in Vietnam to implement a so-called people’s war strategy against its rival organisations. This was especially implemented against the organisation’s former ally, Inkatha, led by Chief Mangosuthu Buthelezi.
