Documentary made by journalist Geraint Talfan Davies and Ed Talfan, a creator of Hinterland, about their relative Idris Morgan and his witness to events in Berlin during the 1930's.
From the BBC website bbc.co.uk/programmes/b04dg4km: "Journalist and broadcaster Geraint Talfan Davies journeys to Berlin to uncover the story about his uncle, Idris Morgan, a young Welshman witnessing Nazi power at first hand in the 1930s. His uncle's diary is his only guide as he unveils the story of a friendship with a young German girl and her mysterious death - a death that brought Idris face to face with Wilhelm Brückner, Adolf Hitler's chief adjutant, only days before the massacre of the Night of the Long Knives. This is a personal story of a dark epiphany, as well as a moving tale of an ordinary family adjusting to the growth of Hitler's power."
Broadcast by S4C on 15th June 2014 and by BBC One Wales on 12th August 2014.
