Ewan McGregor's Cold Chain Mission
Ewan McGregor (Trainspotting, Moulin Rouge, Star Wars: Revenge of the Sith) is an ambassador for UNICEF. In this BBC documentary he travels to the Congo in a race to vaccinate the Baka Pygmy children in one of the remotest places on Earth, before the heat destroys the medicine.
Travelling by helicopter, foot and boat, he journeys through some of the most inhospitable jungles and swamps in the world to make his deadline, learning about the culture of Congo's tribes along the way.
