During the Second World War the Nazis snatched 200,000 Aryan-looking Polish children from their mothers to replenish the "master race" back in Germany. This film tells the extraordinary story of two cousins who were stolen on the same day, 4-year-old Alojzy and 10-year-old Leon. Alojzy was adopted by a "good" Nazi family and soon forgot his Polish past, becoming a model German. When Alojzy was told at age 12 of his Polish parentage, he was horrified, believing the Poles to be Untermensch ("less than human"). It was years before he could accept his real mother and years before the Polish people forgave him his German identity.

Fifty years ago Bomber Command launched a massive campaign against Nazi Germany - the Battle of the Ruhr. In this special edition Jonathan Dimbleby explores the military and moral issues posed by a form of warfare which, since the end of the war, has become a matter of great contention. Was Britain's area-bombing campaign a necessary strategy to defeat Hitler or was it a war crime? The film revisits the industrial city of Essen to hear from Germans who endured the unceasing night-time campaign and, in the studio, Dimbleby questions RAF veterans, victims of the bombing, military historians and those recently involved in policy-making.
