The 1994 HBO mini The Fatherland
, is a great alternative history show. The story revolves around what if the Normany invasion failed and Germany only faced the Russians through the remainder of the war.
The plot is fast forwarded to the mid-1960's when an American reporter visiting the country attempts to uncover the holocaust which was covered up by the Nazi's.
