The 12th century St Donat's castle in South Wales was once home to media mogul William Randolph Hearst - subject of Citizen Kane. Fifty years ago it became the home of Atlantic College, a unique educational establishment bringing together students from around the world in the hope of promoting peace and understanding and to overcome the problems of the Cold War. Felicity Evans explores the campus grounds, meeting students past and present, to find out how an alternative education has influenced their lives. She asks how serving the community and working on the land - including running the organic farm and lifeboat unit - has helped shape their views and plans for the future.
