South Africa’s former president Jacob Zuma is convinced he’s been the target of repeated poisoning attempts. But why? In this episode we dive into the murkiest corners of the long struggle against racial apartheid to uncover Cold War paranoia, toxic underpants, and the origins of Zuma’s fixation with poison.

'Poison' is the story of one man's toxic obsession and the battle for South Africa's future.
