300 years before globalized communication and long before Facebook and Instagram, Leibniz had "friends" all over the world - more than 1,300 mail partners. For the cultural scientist Joseph Vogl from the Humboldt University in Berlin, Leibniz's way of working was something of an "information processing machine". Most of his estate is in Hanover, where Leibniz worked as a librarian and consultant at the Duke's court for 40 years. Leibniz has written so much in his life that so far only a part of the total of 200,000 pages has been recorded and published. It is expected that everything will be edited in 2055. Who was this Gottfried Wilhelm Leibniz who said of himself: "Whoever knows me only from my published writings does not know me"? The film searches for Leibniz as a person. The documentary portrays the genius Leibniz in his time and always brings him back to our present. Different people have their say, and their work would not be possible without Leibniz.

Leibniz: Auf der Suche nach der Weltformel

October 2018 was the four-hundredth anniversary of the outbreak of the Thirty Years' War. The documentary traces the story of how it was finally brought to an end with the peace of Munster and Osnabruck – the first peace in European history to be concluded at the negotiating table and not fought on the battlefield.
