After forcing her to sit and drink with the prostitute, Franz brutally throws Livia out of his rooms. She finds herself in the streets, filled with drunken, amorous Austrian soldiers. Livia realizes that she still has Franz's letter, but nothing remains now except mutual self-destruction. Her sanity slipping, Livia heads to the headquarters of the Austrian Army, where she hands Franz's letter to a General, thereby convicting Franz of treason. Although the General sees that Livia is acting out of spite for being cuckolded, he is forced to comply and Franz is executed by firing squad. Livia, now insane, runs off into the night, crying out her lover's name.
