Xia Haoren, a doctor of archeology, passed through Hong Kong and went to the Hong Kong Traditional Chinese Medicine Council to visit Professor Mu Gongmao. However, he found that he had been killed bizarrely in his office, with his name and some mysterious symbols left on his hand. The police regarded him as a suspect and controlled him. At the same time, his mentor Professor Bartlett was also murdered at home, and mysterious clues and evidence against him were also left at the scene. The Interpol stationed in Hong Kong received a notification from the British intelligence agency to investigate Xia Haotian, and the detective in charge of the case, Mu Jiayi, happened to be Professor Mu's adopted daughter. She accidentally discovered the clues her father left for Xia Haotian and rescued him. Later, the two discovered that the professor's murder was related to an ancient secret, so they went to Edinburgh to investigate the truth of the incident, and were constantly hunted along the way.
