Act I
In the house of Count Vladimir Andreyevich in St. Petersburg, Desire, valet to the Count (who is the son of the Chief of the Secret Police), and other servants are playing dominoes. They discuss the Count’s marriage the next day to the Princess Fedora Romazov, whose wealth will help pay off his debts. The young groom Dimitri admits Fedora, who is looking for the Count. Dimitri leaves to fetch him, and Fedora admires her beloved fiancé’s home, which she has never seen. Policemen appear suddenly, carrying the wounded Count, followed by Detective Gretch and Dr. Lorek. The French diplomat De Siriex arrives and introduces himself to Gretch; Lorek warns Fedora that the injuries are serious. Gretch questions Fedora and the servants about the Count’s enemies. The coachman Cirillo tells them that he had driven the Count to a club. After 15 minutes, he heard two shots, and then saw someone rush by, leaving a trail of blood in the snow. De Siriex explains that he arrived at this moment and found the Count in a pool of blood, with a revolver that Desire confirms that the Count always carried. Desire remembers that an old woman had delivered a letter to the Count earlier in the day, but when Fedora searches the desk, she discovers that it has been stolen. Fedora accuses Gretch of being unwilling to avenge her fiancé, and she swears on her cross to take vengeance. Dimitri and the others remember seeing a stranger in the house, and the porter Michele recalls that it was Loris Ipanov. Fedora watches through the windows as Gretch leaves to arrest Loris in his house opposite the Count’s. Dr. Lorek enters to announce that the Count has died. Fedora, grief stricken, collapses at the Count’s bedside. Loris escapes.

Act II
At a reception in Fedora’s mansion in Paris, Fedora’s cousin Olga Sukarev introduces an exiled Polish pianist, Boleslao Lazinski, to Baron Rouvel and Dr. Borov. Then, Fedora introduces Loris to De Siriex. She privately tells De Siriex that she is looking for proof of Loris’s guilt but that she is also falling in love with him. Borov, meanwhile, warns Loris of Fedora’s charms, but Loris admits that he has already fallen in love with her. Olga is still flirting with Rouvel and teases De Siriex. Loris tells Fedora not only that he loves her but that she also loves him. Borov and Fedora tell Loris that they are about to leave for Russia. Loris is in despair: Exiled, he cannot follow her. Fedora says that she will appeal the sentence that prevents him from returning to his homeland. As Lazinski plays a recital, Loris tells her that he was falsely accused of laying a trap for the Count, though he is no assassin. Fedora cannot conceal her horror when he reveals that he did kill the Count—as punishment. He promises to return in an hour to tell her all the details. After he leaves, she vows that he will not escape her. The recital finishes and, as couples start dancing, De Siriex reads a telegram about a Nihilist attack on the czar. The party breaks up. In an anteroom, Fedora begins to write a letter, and summons Gretch. She tells him that Loris will return to repeat his confession, so he should wait outside for her signal to arrest him. She sends with him a letter for the Russian chief of police, condemning Loris and his brother Valerian. When Loris returns, he denies Fedora’s accusation that he is a Nihilist involved in the attack on the czar and explains why he shot her fiancé. The Count had been a witness at Loris’s wedding to Vanda, a girl who worked for his mother. The Count and Vanda then fell in love. At Christmas, Loris found out what was happening from Vanda’s maid, so he took some incriminating letters from the Count’s desk. He shows them to Fedora, thus proving that the Count loved Vanda and that his engagement to Fedora was only for money. Loris tells her how he had surprised the two lovers, shot the Count, and was himself wounded. The girl had fled past Cirillo, only to die later of pneumonia. Fedora lies to Loris, pretending that she does not know who his accuser is. He despairs of never again seeing his mother. Fedora weeps for him, ashamed that it is he who has accused him, and promises that she will be like another mother to him. He is about to leave, but she begs him to stay, in order to prevent him from fleeing into the arms of the police. Despite his concerns for her reputation, he does so, and they declare their love for each other.

第二幕 
在費朵拉巴黎宅邸的會客室，她的表姐奧爾加．蘇卡列維將流亡的波蘭鋼琴家博萊斯拉奧．拉辛斯基介紹給盧瓦爾男爵和波洛夫醫生。費朵拉隨即將洛裡斯介紹給德.西裡克斯。費朵拉私下告訴德．西裡克斯，她正在搜集洛裡斯的罪證，但她同時也愛上了洛裡斯。與此同時，波洛夫提醒洛裡斯要當心迷人的費朵拉，但洛裡斯承認自己已和她墜入愛河。奧爾加還在與盧瓦爾和德．西裡克斯打情罵俏。洛裡斯對費朵拉說，不僅他愛費朵拉，對方也愛著他。波洛夫和費朵拉告訴洛裡斯，他們即將動身去俄國。洛裡斯一籌莫展：自己流亡在外，不能與費朵拉同去。費朵拉說她會上訴，對不讓洛裡斯回國的判決提出反對。拉辛斯基彈起了琴，洛裡斯向費朵拉坦白，有人誣陷他謀害伯爵，而實際上他並沒有行刺。洛裡斯透露，伯爵確實死於自己之手，這是報應，此時費朵拉無法掩飾自己的恐懼。洛裡斯許諾，一小時後他會回來，將所有真相向費朵拉和盤托出。洛裡斯離開後，費朵拉發誓，絕不讓前者逃出自己的手心。琴聲停了，大家雙雙步入舞池。德．西裡克斯給眾人讀了一份電報，電報上說無政府主義者襲擊了沙皇。聚會中斷了。費朵拉回到休息室，開始寫信聯繫格瑞奇。她告訴格瑞奇，洛裡斯即將回來供認自己的罪狀，她讓在門外守著，自己一發信號就進來抓人。一同發出的還有一封給俄國員警首腦的信，她在信中告發了洛裡斯和他的弟弟瓦萊裡安。洛裡斯回來後否認了費朵拉的控訴，說自己並非無政府主義者，也沒有參與襲擊沙皇事件，還解釋了自己為什麼會向她的未婚夫開槍。原來洛裡斯曾與一名叫旺達的女子結婚，她為洛裡斯的母親工作，而伯爵正是他們的證婚人。但後來旺達與伯爵發生了婚外情。耶誕節那天，洛裡斯從旺達的女僕那裡得知了內情，便從伯爵的書桌上拿了幾封能證明此事的信。他把信給費朵拉看，信裡寫得明明白白：伯爵鍾情於于旺達，他與費朵拉訂婚只是為了錢。洛裡斯告訴她，這對偷情的男女看到他後驚慌失措，他射殺了伯爵，自己也受了傷，而旺達逃走時經過了西裡洛身邊，沒過多久她便死於肺炎。費朵拉向洛裡斯撒了謊，假裝並不知道指控他的人是誰。洛裡斯因為再也見不到母親而感到絕望。費朵拉也為他垂淚，並因為自己指控了洛裡斯而覺得愧對於他，她向洛裡斯許諾，自己會向母親一樣對他。洛裡斯要離開了，但費朵拉擔心他落入員警的羅網，便懇求他不要走。洛裡斯雖然擔心影響費朵拉名譽，但還是留了下來，兩人彼此表露了心跡。

Act III
Some months later, in the garden of Fedora’s villa in Switzerland. Loris and Fedora are deeply in love. As they embrace, Olga enters and tells them she has renounced the world and is tired of the beauties of nature. Loris suggests finding a companion and leaves to collect some letters from the post office. De Siriex arrives and tells them that he was just passing by and decided to visit. Olga tells them that she has become bored with Lazinski. De Siriex suggests that Lazinski might have been a secret agent. After a brief fainting spell, Olga leaves to change for bicycling. De Siriex admits to Fedora that he came to talk to her about Loris. The Count’s father, the chief of police, arrested Loris’s brother Valerian as a Nihilist conspirator, and the young man died in prison. On hearing this news, Loris’s mother died. Fedora realizes that it was her letter that brought about both of these deaths. Olga reappears, and she and De Siriex go off bicycling. As a peasant boy is heard singing, Fedora pleads with God not to save her, but he should save her beloved. Loris returns from the post office with a telegram from Borov announcing his imminent arrival and that Loris has been pardoned and is now free to return to his Country and family. One of the other letters is also from Borov but was sent earlier. It tells of a letter sent by a woman in Paris informing the chief of police of Loris’s confession, which led to his brother’s accidental drowning in prison and the death of his mother. Loris vows vengeance on this woman and is determined to unmask the woman in Paris, but Fedora tries to defend her. Loris suspects that Fedora knows the identity of the woman, and then realizes the truth. She begs that he pardon her for having caused the deaths of his brother and mother. In his fury, he is ready to kill her, but she drinks the poison which she keeps in a secret compartment in her cross. Loris forgives the dying Fedora as the peasant boy is heard singing in the distance.
