The paths of guests and employees cross at the Palace Hotel in St. Moritz: A chambermaid experiences financial difficulties. A guest has been robbed. A thief is caught. An assistant cook is promoted to waiter. And there’s no shortage of love in this small world of the great Hotel Palace. Keeping an orderly eye over proceedings is the hotel’s beautiful patron, whose heart is in the right place.

If any one man is responsible for the rejuvenation of the postwar Swiss film industry, that man was director Leopold Lindtberg. Matto Regiert (Madness Rules) was co-adapted for the screen by Lindtberg from a novel by Friedrich Glauser. Heinrich Gretler stars as Police Constable Studer, the hero of several of Glauser's most popular works. This time, Studer must solve the murder of the director of an insane asylum -- and it's not (surprise, surprise) the most likely suspect, manic-depressive patient Herbert Caplaun. For box-office purposes, Matto Regiert stresses a romantic subplot involving Caplaun and nurse Irma Wasem.

Gilberte Montavon was a legend in her own lifetime. As a young woman, she was confidante to hundreds of thousands of Swiss-German speaking soldiers during the First World War, and remembered most of their names. She was still a teenager when the war began, and was immortalised by a song written during the war years by the Swiss-German bard and lute player, Hans Inn der Gand.

Operetta (German: Operette) is a 1940 musical film directed by Willi Forst and starring Forst, Maria Holst and Dora Komar. The film was made by Wien-Film, a Vienna-based company set up after Austria had been incorporated into Greater Germany following the 1938 Anschluss. It is the first film in director Willi Forst's "Viennese Trilogy" followed by Vienna Blood (1942) and Viennese Girls (1945). The film portrays the life of Franz Jauner (1832–1900), a leading musical figure in the city. It is both an operetta film and a Wiener Film.
