How South Africans fought to win their freedom, and the Australians who helped them fight for it.

It's 1990, and the world is watching as Nelson Mandela walks free from his prison cell after 27 years.

The global movement to end the racist policy of Apartheid in South Africa is finally on the brink of victory.

Host Sisonke Msimang grew up in a family of South African freedom fighters, and in this series, she talks to South Africans who risked their lives in the struggle to end apartheid.
