In Warsaw, by chance, Karl is asked to play at a private party where he once again crosses paths with Tania. She is being escorted by General Boris Alexandroff (Gustav von Seyffertitz), the infatuated head of the Russian Military Intelligence Department. Foolhardily, Karl plays a tune from the opera they attended together. She recognizes it, but does not betray him. As the party goers are leaving, she slips away for a few stolen moments with her love. The jealous Alexandroff suspects their feelings for each other. He hires Karl to play the next day at a ball he is giving at his mansion for Tania's birthday.
