ACT ONE
The Grand Duke secretly leads a lady through the chambers of Tsarevich Alyosha. The young heir is only interested in physical exercise and books – he strictly rejects any female presence. His aversion to women has caused a serious rift with his father, the Tsar. As they leave, the lady forgets her handbag. Ivan, the Tsarevich’s loyal valet, hides it quickly to prevent any trace of feminine presence from being discovered. Just then, his wife Mascha enters – and upon seeing the handbag, assumes her husband is having an affair. Ivan manages to calm her down and usher her out just in time before the
Tsarevich arrives.
Alyosha is lonely and conflicted. The Grand Duke presents him with portraits of potential brides, but Alyosha refuses.
He decides to go out and is driven by carriage to a small theatre on the outskirts of the city. Backstage, a young man named Kautschukoff is preparing for his performance. As Sonja, he steps onto the stage. The Tsarevich is captivated and sends an invitation for a private meeting.
Kautschukoff visits Alyosha, bringing along Sonja’s costume. The two grow closer. Alyosha confides that his father insists he find a suitable bride. Kautschukoff has a simple solution: he transforms into Sonja. The two drink, laugh, and decide to stage a performance for the court.
ACT TWO
Mascha again grows suspicious – this time, it’s a lady’s shoe left behind by Sonja. Ivan must once more pacify his jealous wife.
The Grand Duke, having heard of the affair, is delighted that the Tsarevich finally seems interested in women. Still, he cautions Alyosha not to take the relationship too seriously and to continue seeking an appropriate match. Alyosha prepares to give a speech to his regiment and dons his dress uniform.
During the speech, the Grand Duke urges Sonja to release the Tsarevich under the pretense that she was only playing with his feelings. Sonja hesitates, but under threat of being removed from court, agrees. The Grand Duke announces the imminent arrival of Princess Miliza, chosen by the Tsar as a bride for his son. Alyosha refuses to meet her.
Suddenly, Sonja bursts in with fellow performers from the theatre, hoping to lift Alyosha’s spirits.
The Grand Duke, secretly entertained, abruptly ends the charade by claiming that Sonja confessed to him that she does not truly love Aljoscha. He declares Sonja must leave the court. Shocked, Alyosha consents to marry Miliza. Kautschukoff can no longer maintain the lie. He reveals he was blackmailed by the Grand Duke. At last, Alyosha declares his love for Kautschukoff – and Kautschukoff returns his feelings.
ACT THREE
Alyosha and Kautschukoff have fled to Italy, where they enjoy a life of freedom and love.
Ivan and Mascha have followed – and both begin flirtations of their own: Ivan with Lina, Mascha with Bordolo. When these affairs are discovered, a heated argument breaks out. But their Italian companions show them that love need not be taken so seriously.
The Grand Duke tracks down the runaway couple. He pleads with Kautschukoff to end the relationship – under current circumstances, there can be no future for the two. Kautschukoff sees the painful truth.
Finally, the Grand Duke delivers the news: the Tsar is dead. Alyosha must return and assume his role as emperor – and he obeys.
