The action of the novel takes place from 14 to 20 April 1964, as Germany prepares for Hitler's 75th birthday celebrations, which are to take place on the latter date. A visit by US President Joseph Kennedy is planned as part of a gradual détente between the United States and Germany. The novel suggests that the Nazi hierarchy is eager for peace since its efforts to settle the conquered East are failing because of the continued resistance from Polish and Soviet partisan movements. The Nazis have also failed to instill their ideology into the younger generation, many of which have turned away from the regime, but active opposition is limited.
