Herbert Krcal (Roland Düringer) and his wife Margit (Nina Proll) dream of owning a home. They prefer to do this in the "Blue Lagoon", a prefabricated house park in the south of Vienna, where they regularly go on pilgrimage with their son Philipp. Just as regularly, they have to recognize the bitter truth that they cannot actually afford the dream house they have visited.
Der Graf von Luxemburg (The Count of Luxembourg) is an operetta in three acts by Franz Lehár to a German libretto by Alfred Willner, Robert Bodanzky, and Leo Stein. A Viennese take on bohemian life in Paris at the beginning of the 20th century, the story revolves around an impoverished aristocrat and a glamorous opera singer who have entered into a sham marriage without ever seeing each other and later fall in love at first sight, unaware that they are already husband and wife.
In the made-up country of Alanien, King Alexander I has been overthrown while abroad. Now, he's in Vienna with his daughter, the city of his fondest memories since studying there as a boy. It doesn't take long for the charm of Vienna to work its magic on the former king: he quickly comes to terms with the new situation and is able to enjoy the Austrian capital sans all the ceremony and trappings which would otherwise accompany him on a state visit. The princess is content with preparing herself for a career as a pianist concert, while the former king takes a job as a chauffeur in the embassy of the country he once ruled. The revolutionaries are shocked; and his days in Vienna are numbered.
