In Ernst Lubitsch in Berlin, the first-ever feature documentary on the inventor of the "Lubitsch Touch", Lubitsch's daughter Nicola guides us through her father's exciting time in Germany, supported by an illustrious group of film historians, Lubitsch experts and some of today's most influential German film directors. Rare film clips, newly discovered photographs, newsreel footage and original audio recordings with actress Henny Porten, other first-hand witnesses and Lubitsch himself round off this comprehensive portrait of one of cinema's few true geniuses.

The film follows Kaspar Hauser (Bruno S.), who lived the first seventeen years of his life chained in a tiny cellar with only a toy horse to occupy his time, devoid of all human contact except for a man who wears a black overcoat and top hat who feeds him.

Nine fictitious documentaries and films reflect the mood of late 1970s Germany, particularly the two-month period in 1977 when a businessman was kidnapped by the RAF (Red Army Faction). The kidnap had been made to orchestrate the release of the original leaders of the RAF, aka the Baader-Meinhof.
