In the early years of the Republic of China, Mr. Shen Da, a great jeweler, died suddenly without illness, and Master Shen, who was extremely sad, waited in front of his father all day. Late at night, a dagger with a black post flew into the Shenfu mourning hall. The post said: Master Shen, the finger-cutting group will come to win people's hearts in three days! The next day, the old housekeeper of Shenfu invited the detective Du Yifu and his daughter Heather. On the third day, Miss Shen, who was studying in other cities, came back to attend the funeral. Persuaded by his father's friend and President Sun of the Chamber of Commerce, Master Shen accompanied his sister to the cemetery to pay tribute to his father, and was shot by gangsters. In the hospital, Shen Fu wailed around the dead Master Shen, while President Sun stared at Master Shen's pale face with suspicious eyes. All this was seen by Du Yifu disguised as a medical doctor, so he turned to his military friend Wang Yingchang for help and held President Sun in the form of kidnapping. A few days later, Du Yifu got important clues from Master Shen, who was recovering gradually. It turns out that Mr. Shen Da has a rare treasure-Eight-Qiao Beads. After Shen Da's death, Master Shen discovered that the orb had been stolen. He realized that his father's death must be related to the orb, so he told President Sun his doubts. Since then, disasters have fallen on him one after another. Du Yifu concluded that this was a major case of stealing national treasures. In addition to the finger-cutting group, some important people in politics may also be involved, and the most suspicious one is Wu Xiren, the finance minister. Wu Xiren has twin sons, and his younger brother Anbang is a kind college student. My brother Ding Guo is a dude. At this point, the following refers to the group's eyes on Wu Dingguo. Du Yifu concluded that Wu Xiren was probably the one who murdered Shen Da and stole the orb. As it happens, Wu Dingguo was killed by the finger-broken group on the way to abscond with the orb, and Heather took the orb back from the finger-broken group. To the surprise of both sides, it was a fake orb. The finger-amputees were angered. They assassinated President Sun, kidnapped Miss Shen, and took Wu Xiren to the residence of Ruth, a businessman from G country in the concession area. In the middle of the night, Du Yifu sneaked into Ruth's bedroom and cut off the eight pearls. However, this action led to Du Jia's being copied, Master Shen lost his treasure again, Heather was imprisoned to save his father, and Du Yifu almost died. A mysterious phone call enabled the detective to seize the favorable fighter again and recapture the eight-trick pearl from Ruth. On his way home, Du Yifu met an old man with white hair. It turned out that he was Cui Yi, the founder of the Finger Broken Group who was killed and imprisoned 16 years ago, and Heather was his own daughter. The case was finally settled, but what was waiting for the detective was a wanted order. Du Yifu resolutely sank the orb into the deep pool, bid farewell to her adopted daughter Heather, and became a monk and lived in seclusion.
