Two UFA employees travel by car from West Berlin to Potsdam's Sanssouci Palace together with Ministerial Director Schimmelpfennig to persuade Frederick II, who haunts the palace, to collaborate on a new film about himself. The daily newspaper Die Welt had already written about the fact that at the founding meeting of the new UFA, its director pointed out under the motto: "The old spirit lives" that the monumental film Fridericus Rex - Eleventh Part was a first contribution to the ideological armament of the Free World.
Unfortunately the movie Das Stacheltier: Fridericus Rex - Part Eleven is not yet available on HBO Max.
