To the Sherlock Holmes, the King of Bohemia appeals for help. Once the king had a stormy romance with the famous opera diva Irene Adler, but now he is going to marry a woman of his descent. Irene blackmails his former admirer, threatening to send a compromising photo to the bride’s family and upset the wedding. Despite the fact that various attempts were made to get the picture – hired burglars and robbers, searched Irene – the card could not be found. Remains the last resort – the help of the famous detective.
To fulfill the commission, Holmes changes into an unemployed groom and goes to the Irene house. Helping the servants to take care of the horses, he learns that Irene is the most charming creature of all, wearing a bonnet. She leads a modest lifestyle, sometimes gives concerts and after lunch leaves for a walk. She is visited by a lawyer, Godfrey Norton. The detective decides what this Mr. Irene may be. Meanwhile, he appears himself and with Irene
leaves for the church. Holmes follows them. In the church Irene and his companion approach the priest with the request to marry them, but he refused to perform the rite without witnesses. The appearance in the church of Holmes in the groom’s clothes solves the problem: a wedding takes place.
In the evening of the same day Holmes, disguised as a priest, again goes to the house of Irene. The people hired by them attack the woman leaving the carriage. Holmes rushes to her aid and with a face smeared with specially painted red for this purpose falls to the ground. The people of Irene bring the detective into the house and, at his request, open the window. Standing in the street, Watson throws a smoke flare into the room. There is a panic, during which Irene first rushes to the hiding place, which holds the coveted picture. Taking advantage of the general confusion, Holmes leaves the house. When he enters his apartment on Baker Street, the passing young man wishes him good night. Holmes is perplexed: where did he hear this voice?
The next day, Holmes, Watson and the King of Bohemia come to the house of Irene,
but the house is empty, and for the great detective a letter is left. Irene figured out who the priest was to whom she had sheltered in her house and made sure of that when she changed into a man’s suit to wish Mr. Sherlock Holmes goodnight. Irene will not obstruct the marriage of the king, she married a loved one and leaves England forever. The photo she takes with her, and in return leaves her to remember.
Such a turn of affairs of the king suits. As a payment for services, he offers Holmes a ring with an emerald. But the great detective refuses: the picture of Irene is the best reward.
Holmes, who always mockingly spoke of the woman’s mind, suffers defeat from a woman. Irene Adler becomes for him the ideal, the only woman who managed to outwit him, the one he calls “That Woman”.
