A German-language film loosely based on the 1883 operetta Eine Nacht in Venedig (A Night in Venice) by Johann Strauss II. The film was also made into separate Hungarian-language version Egy éj Velencében based on the same screenplay. The two versions were shot simultaneously. The Hungarian version was co-directed by Wiene and Géza von Cziffra and used a separate cast of Hungarian actors. From Wikipedia.

The story takes place in a small village manor-house off Vásárosladány. Sándor leads a quiet life with his wife, son and the now poor relatives of his wife, one which is characterized by the monotony of rural boredom. The arrival of another poor relative, Kitty, a young girl brought up in America, whose way of thinking reflects modern times, puts an end to this overwhelming monotony.
