When the USSR collapsed it could no longer support North Korea, leading to hundreds of thousands of deaths due to starvation and malnutrition. We hear from one survivor and Prof Hazel Smith who explains some of the contributing factors behind the 'long, slow famine'. Also on the programme, the bombing of the Rainbow Warrior, why the UK sent all its gold to Canada during World War Two, battling for Roma rights and the mystery behind Cuba's blindness epidemic. All told by the people at the heart of the stories.
