In 1912, the Austrian secret service identifies Marcella Galdi, an Italian noblewoman who is visiting Vienna, as an Italian spy. To avoid diplomatic confusions, she is kidnapped while dancing with the Austrian General Staff officer Michael von Hombergk at a ball at the famous hotel Sacher in Vienna, and sent back to Italy. Shortly afterwards, a secret plan of an Austrian fortress appears in Hombergks office desk, and as he himself is unable to explain this, the secret service urges him to commit suicide, but instead he manages to escape from Vienna.
