The Play on One S04 E03 Escape from Kampala

Wycliffe Kato, Director of Civil Aviation in Idi Amin's Uganda, is catching a flight to Canada for a conference when he's arrested by Amin's secret police, members of the notorious Sate Research Bureau, and thrown into the Nakasero prison. This should have meant certain death, but, along with his cellmates and army officers under suspicion of organising a coup, Kato escapes and travels on foot to Nairobi.
