Der schwarze Domino (1929)

A masked ball at the court of the Spanish king in Madrid. The embassy attaché of the Republic of the Morea in Paris, the somewhat easy-going Horace de Massarena, and the still young Count Juliano have arrived and begin to chat animatedly. Massarena tells his interlocutor that exactly a year ago in this very salon - also on the occasion of a masquerade ball - he was able to do a favor to an unknown woman masked as a black domino.
