《A Scandal in Bohemia》adapted.

During the tense moment of Holmes and Moriarty's life-and-death struggle, the arrival of a mysterious phone call changed the situation of the battle.On the other end of the phone, a voluptuous woman's hand appeared on the screen, holding something that Moriarty desperately desired.At the same time, Sherlock Holmes and Watson returned to Baker Street and continued to deal with various cases.Sherlock became an Internet celebrity because of Watson's blog, attracting more people seeking help, but most cases seemed extremely boring in their eyes.

One day, a fainted man was welcomed to Baker Street, and the case he brought was about the death of a travel companion.Sherlock decided that the case was not worthy of his personal involvement, so Watson went to the scene to investigate on his behalf.However, during the video communication between the two, uninvited guests suddenly appeared on Baker Street. They asked Sherlock to put on formal clothes and go to a certain place.At the same time, Watson also received a helicopter pickup invitation.

It turns out that all this was arranged by Sir Mycroft, and they were invited to Buckingham Palace to meet with a high-ranking client.The client is in trouble when indecent photos fall into the hands of Irene Adler, and Mycroft wants Sherlock to retrieve them.At this time, Irene also received Sherlock's photo, and a contest about wisdom and courage quietly began.

Sherlock sneaks into Irene's house pretending to be robbed and witnesses the naked Irene.Irene unabashedly pointed out Sherlock's purpose, and Watson triggered the fire alarm at the door, causing Irene to look in the mirror in the room in panic, allowing Sherlock to discover the location of the safe.Just as Sherlock was about to crack the code, several Americans with guns broke into the room and forced Sherlock to open the safe.

Faced with the crisis, Sherlock, Irene and Watson teamed up to subdue the enemy and took the opportunity to steal the secret mobile phone in the safe.However, they are soon discovered, and Irene injects Sherlock with a coma agent and escapes.Although Sherlock suffered a loss in this confrontation, when he chatted with Irene about the death of his friend, he felt that heroes cherish heroes“ and developed a good impression of her.

After Mycroft discovered that the US Intelligence Agency was involved in the matter, he warned Sherlock not to interfere with Irene's affairs.At Christmas, there was a party in Baker Street, and Sherlock received a gift from Irene - the mobile phone.In the morgue, Sherlock found Irene's disfigured body and was very depressed.However, Irene suddenly appeared and took Watson away, telling Watson that she was not dead, hoping that Watson could get her phone back from Sherlock.Sherlock followed Watson and found that Eileen was still alive. After returning to Baker Street in a daze, he found that American intelligence agents had kidnapped the landlord Mrs. Hudson and asked him to hand over his mobile phone.Sherlock realizes that the contents of the phone are not just pornographic photos, he cleans up the gangsters and rescues Mrs. Hudson.

Erin came to Baker Street in distress. The password setting on her mobile phone was ”I'm_ _ _ locked“ (I was _ _ _ locked), and she needed to fill in the password in the middle.Sherlock tried several times without success, so he had to hand the phone to Irene.Irene had an email password from the National Security Agency, and Sherlock cracked it for her. It turned out to be the flight number where the terrorists wanted to put a bomb on the flight.Irene secretly sent the message to Moriarty, and then Moriarty sent a text message to Mycroft mocking the British Intelligence Department.After Mycroft knew that the plan was exposed, he asked Sherlock out.

It turns out that both the United Kingdom and the United States have undercover agents at the top of the terrorist hierarchy who leaked the bomb plans to the intelligence department.But in order to protect the safety of the undercover agents, they could not directly prevent the terrorist attack, so they used corpses to disguise themselves as passengers to confuse the terrorists.However, after this plan was cracked by Sherlock, Irene revealed it to Moriarty, who had connections with terrorists, causing the plan to fail.Erin used the remaining secrets in her phone to blackmail Mycroft into exchanging a large sum of money and her own safety. She admitted that she was playing tricks on Sherlock.

However, Sherlock understood Eileen's feelings for him through the way her pulse quickened and her pupils dilated when they spoke.So he solved the code ”I'm sher locked% (I was trapped by Sherlock), revealing that Eileen was in love with Sherlock.Irene knew that her life was in danger without the secret in hand. She asked Sherlock to help her, but Sherlock left without saying anything.A few months later, Mycroft came to Watson and told him that Irene had been beheaded by terrorists. He hoped that he would not tell Sherlock the truth and that Irene was being protected as a witness in the United States.Watson told Sherlock this, and Sherlock asked to keep Eileen's camera phone for him to keep as a souvenir.

There are many text messages from Eileen to him on the phone, most of them are "Let's have dinner together", and the last one is to say goodbye to him.The scene shifted to the scene where Irene was beheaded. Irene sent her last text message to say goodbye to Sherlock and then resigned to her fate and closed her eyes.But then she heard the special text message tone she had set for Sherlock, turned around and saw Sherlock killing people disguised as a terrorist, and said to her: "When I say run, you run."“Sherlock will always remember Irene as ”that woman% - the only woman who has defeated him.
