An American historian (Mr Webster) comes to Berlin to visit an old man who claims to be the real Adolf Hitler and to be 103 years old. The Hitler who died in 1945, the old man says, was just one of his six doubles - one for each weekday - while Hitler himself retired into a bunker below the S-Bahn tracks and married a second time. After much deliberation and identity-searching, Mr Webster ends up shooting and killing the self-proclaimed Hitler.
