In Munich on the 27th of March 1952 preparations were made to assassinate the German Chancellor Konrad Adenauer. A young man was supposed to detonate a bomb in his proximity. That same day the terrorist attack ended in unexpected fashion. The police tried to find the man behind the attacks for decades - without success. It was 50 years later, in winter 2002, that the journalist Henning Sietz - author of the controversial book “Attack on Adenauer” - rediscovered the files of the investigation in a public archive. After extensive research together with filmmaker Matthias Unterburg in archives in Germany, the USA, France and Israel, he has reconstructed the secret story of an attempted political assassination in a tense TV documentary... which comes up with some surprising results.
