In 1885, famous New York Metropolitan Opera singer Maddalena dall' Orto is scheduled to perform at a festival in the German residence of Ilmingen.

Originally Liebeswalzer, this German operetta was the third talkie vehicle for the effervescent Lillian Harvey. The plot is a typical Graustarkian affair, with Princess Eva (Harvey) preparing to marry a duke whom she's never met. Getting cold feet, the duke ducks the wedding, persuading a handsome young commoner named Bobby (Willy Fritsch) to take his place. The wedding goes on as planned, with Eva never suspecting that her new hubby is a ringer. Eventually, the false duke confesses everything, leading to all sorts of intrigue before a happy ending can be realized. Love Waltz was simultaneously filmed in an English-language version, which posed no problem for the British-born Harvey but caused a few uncomfortable moments for her Teutonic co-stars (eventually, Willy Fritsch was replaced by John Batton, who'd played a bit role in the German version).

Drama by Romano Mengon

Panicked that he might feel obliged to marry Andrea, Jan escapes from this place. Andrea is deeply disappointed and seeks revenge. Out of spite, she becomes involved with the falconer Bartel and is later raped in a wooden hut. The centigress, concerned about morals and customs, then sends Fundvogel to a convent.

In her despair, Fundvogel then throws herself off a bridge into the floods with suicidal intent.

The young student Mary spends the beginning of her holiday with boat trips, visits to her wealthy groom, and gardening.
