Part of "Life on the Edge" series. In 1984 Charles Stewart shot the first film to alert the world to the terrible famine taking place in Korem, Ethiopia. It helped trigger the 1985 Live Aid concert, leading in turn to the largest public donation of aid from around the world ever seen. Now in his 70s, Charles and his partner Pat Scott Robson return to Ethiopia to donate their film archive to the Ethiopian National Archive, and travel across the country to revisit some of the people they've filmed over quarter of a century.
