In the late Qing Dynasty, Sherlock Holmes, a British detective, and his friend Watson visited China, only to find that the inn was heavily guarded when they stayed at night. Before Watson knew what was going on, the news came that General Booker, who was sent by the British government to escort a batch of boxer indemnity jewels, was assassinated and the jewels were gone. The imperial envoy found Sherlock Holmes who stayed here, and everyone tried their best to ask Holmes to solve the case. Before Holmes could figure out the clue of the case, Booker's head was gone again. In Tanggu town, Holmes found a white ponytail that was the same as that held in the palm of the horse dealer Jinma. He talked about the case with Tu Youyou, the commander-in-chief of the Qing army, and knew that the Golden Horse Palm had extremely high martial arts. At this moment, Bai Furong, the owner of Xianlai Inn, appeared. Bai Furong is the adopted daughter of Golden Horse Palm and a member of the Boxer Rebellion. She gave the news to Golden Horse Palm first. When Holmes arrived at the horse factory, it was empty, but he found Booker's head. After visiting the scene again, Holmes visited Henry, the British minister. Henry told him that Booker was in charge of shipping and helped Booker in the hut where he had studied in England. Holmes returned to Xianlai Inn. Bai Furong inquired about the whereabouts of the jewels from his childhood friend Tu Youyou, and suspected that the jewels had been taken away by foreigners' lackeys and comprador Wencai Du. Du Wen was drooling over Bai Furong's beauty, suspecting that the disappearance of jewelry was related to her, so after she fainted in ecstasy, she was sent back to the house. When Furong wakes up, Wencai Du asks her about the jewels. Furong knows that Wencai Du didn't steal the jewels. But we still don't know who did it. On the occasion of his birthday, he invited guests to kill Holmes, Watson and Tu Youyou, but Tu Youyou and Zhang moved first to save Furong. In a scuffle, Tu Youyou died to save Furong. Wencai Du finally found the jewels on the lawn of the legation, and got carried away. All the Boxers were led by Jin Mazhang, and Holmes came to help and killed Wencai Du. The boxer was about to take back the jewels when Henry, the British minister, appeared. It turns out that he is the real treasure thief. In order to keep the jewels for himself, he asked his student, General Tuwu, to bury them on the lawn, and Booker only escorted several boxes of stones. Henry also died for jewelry. The boxer finally regained the treasure for the country. Holmes forged a deep friendship with Golden Horse Palm, Furong and others.
