Story:
This operetta tells the story of the queen of Petra, who has a little girl seven years old. Her husband, the king, is at war with the Romans. The Romans, who are losing, kidnap the little daughter and hold her as a hostage. They then warn Petra that dire consequences will ensue unless she tells her husband to stop fighting. Petra refuses to pass this ultimatum on to the king, and the Romans execute the girl. Her husband wins the war and saves the country. He returns as a conquering hero, but his joy ends when Petra gives him the sad news about his daughter.
