Out of love for Franz, she is nevertheless prepared to put up with all the hardships and duties. She knows that she must first earn the respect of the court. Sisi finds a friend and confidante in Fanny, whom she smuggles into the palace as a maid under a false name.

Sisi is pregnant. The young imperial couple do not have much time to enjoy their happiness together. The conflicts in Hungary come to a head, and the rest of Europe is also seething. Countess Esterhazy hopes that Sisi can persuade the Emperor to negotiate with the Hungarian nobility. She arranges a secret meeting between Sisi and Count Andrassy. But before she can speak to Franz, an assassination attempt is made on him during the christening of their daughter Sophie.
